export const CommonCacheCleanup = () => <>
    <p>Arc automatically cleans up the resource cache. This process runs in the background during every receive cycle and removes stale cache entries for files that are no longer present on the remote server. This keeps the cache size manageable without requiring any manual action.</p>
    <p>By default, files are retained for 30 days, but you can use the <code>ResourceCacheRetentionDays</code> setting in the <strong>Other Settings</strong> field on the <strong>Advanced</strong> tab to adjust it to fit your environment. For example, <code>ResourceCacheRetentionDays=15</code> retains files for 15 days before removing them.</p>

export const SlasTab = ({siteName = "CData Arc"}) => <>
    <p><em>Settings related to configuring Service Level Agreements (SLAs).</em></p>
    <p>
      SLAs enable you to configure the volume you expect connectors in your flow to send or receive, and to set the time frame in which you expect that volume to be met. {siteName} sends emails to warn the user when an SLA is not met, and marks the SLA as <em>At Risk</em>, which means that if the SLA is not met soon, it will be marked as <em>Violated</em>. This gives the user an opportunity to step in and determine the reasons the SLA is not being met, and to take appropriate actions. If the SLA is still not met at the end of the at-risk time period, the SLA is marked as violated, and the user is notified again.
    </p>
    <p>
      To define an SLA, toggle <strong>Expected Volume</strong> on, then click the <strong>Settings</strong> tab.
    </p>
    <img src="/public/images/sla_empty.png" alt="SLA Empty" />
    <ul>
      <li>If your connector has separate send and receive actions, use the radio buttons to specify which direction the SLA pertains to.</li>
      <li>In the <strong>Expect at least</strong> portion of the window:
        <ul>
          <li>Set the minimum number of transactions you expect to be processed (the volume)</li>
          <li>Use the <strong>Every</strong> fields to specify the time frame</li>
          <li>Indicate when the SLA should go into effect. If you choose <strong>Starting on</strong>, complete the date and time fields.</li>
          <li>Check the boxes for the days of the week that you want the SLA to be in effect. Use the dropdown to choose <strong>Everyday</strong> if necessary.</li>
        </ul>
      </li>
      <li>In the <strong>Set status to 'At Risk'</strong> portion of the window, specify when the SLA should be marked as at risk.
        <ul>
          <li>By default, notifications are not sent until an SLA is in violation. To change that, check <strong>Send an 'At Risk' notification</strong>.</li>
        </ul>
      </li>
    </ul>
    <p>
      The following example shows an SLA configured for a connector that expects to receive 1000 files every day Monday-Friday. An at-risk notification is sent 1 hour before the end of the time period if the 1000 files have not been received.
    </p>
    <img src="/public/images/sla_defined.png" alt="SLA Configuration Example" />
    <Note>
      You can turn off SLA alerts if necessary. This can be useful during maintenance windows. Click <strong>Settings</strong> on the navbar, then navigate to <strong>Alerts &gt; General Alerts</strong>. Click the tablet and pencil icon to edit, and uncheck the <strong>SLA Alerts</strong> setting.

    <p><em>Settings related to configuring alerts.</em></p>
    <p>
      Before you can execute Service Level Agreements (SLAs), you need to set up email alerts for notifications. By default, {siteNameShort} uses the global settings on the <a href="/26.3/self-hosted/en/getting-started/administration/settings/alerts">Alerts</a> tab. To use other settings for this connector, toggle <strong>Override global setting</strong> on.
    </p>
    <p>
      By default, error alerts are enabled, which means that emails are sent whenever there is an error. To turn them off, uncheck the <strong>Enable</strong> checkbox.
    </p>
    <p>
      Enter a <strong>Subject</strong> (mandatory). Check <strong>Allow {siteNameShort}Script in Subject</strong> to use {siteNameShort}Script in the <strong>Subject</strong> field. When you select this, the <strong>{siteNameShort}Script Editor</strong> button appears (<img src="/public/images/rest_arcscript_editor.png" alt="arcscript editor button" style={{

RSS Connectors support downloading remote RSS and Atom feeds.

## Key Capabilities

* RSS and Atom feed consumption with automatic polling and multiple authentication schemes
* Incremental update support using If-Modified-Since headers and ETag-based duplicate detection
* Configurable response header promotion for metadata extraction

## Overview

RSS connectors expose a simple interface to automatically poll for downloadable content from a specific RSS or Atom feed. The connector can be configured to only process new and updated content, and can perform both HTTP and TLS authentication to the remote service.

## Connector Settings

### Settings Tab

#### Configuration

*Settings related to the core configuration of the connector.*

| Setting                   | Description                                                                                                                                                                                                                                                                                                      |
| ------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Connector Id**          | The static, unique identifier for the connector.                                                                                                                                                                                                                                                                 |
| **Connector Type**        | Displays the connector name and a description of what it does.                                                                                                                                                                                                                                                   |
| **Connector Description** | An optional field to provide a free-form description of the connector and its role in the flow.                                                                                                                                                                                                                  |
| **Feed URL**              | The HTTP or HTTPS endpoint from where RSS content should be downloaded.                                                                                                                                                                                                                                          |
| **Feed Type**             | Whether the remote URL is an RSS or Atom feed.                                                                                                                                                                                                                                                                   |
| **Use If-Modified-Since** | When enabled, the connector includes an If-Modified-Since header in the outgoing request that equals the latest publication date and time from the previous download attempt. This causes the server to filter responses based on what content is new or has been modified recently.                             |
| **Process New Items**     | When enabled, the connector stores the last modified date from previous downloads, and filters out results that are not new or modified since that date. The result is the same as **Use If-Modified-Since**, but the filtering is done on the client-side rather than sending a filter condition to the server. |

#### Authentication

*Settings related to authenticating with the RSS service.*

| Setting                | Description                                                                                                            |
| ---------------------- | ---------------------------------------------------------------------------------------------------------------------- |
| **Authorization Type** | The type of authentication to use with the RSS service. See the [Authentication](#authentication) section for details. |

#### TLS Server Authentication

*Settings related to verifying the TLS server's identity.*

| Setting                    | Description                                                                                                                                                                                                                                                                                                                                                                    |
| -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **TLS Server Certificate** | The public key certificate used to verify the identity of a TLS server. You can upload a certificate, leave the field blank to allow the underlying OS/JVM to perform certificate validation, or set it to `Any Certificate` to trust the target server's identity. Use Any Certificate with caution: the certificate verifies that you are connecting to the intended server. |

### Advanced Tab

#### Advanced Settings

*Settings not included in the previous categories.*

| Setting                   | Description                                                                                                                                                                                                                                                                                                  |
| ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Include Channel**       | Whether to include data about the RSS channel in the output.                                                                                                                                                                                                                                                 |
| **TLS Enabled Protocols** | The list of TLS/SSL protocols supported when establishing outgoing connections. Best practice is to only use TLS protocols. Some obsolete operating systems do not support TLS 1.2.                                                                                                                          |
| **Skip Processed Items**  | When enabled, the connector maintains a checksum of each item downloaded, and does not download the same content more than once.                                                                                                                                                                             |
| **Timeout**               | The duration in seconds to wait for a response from the RSS server before throwing a timeout error.                                                                                                                                                                                                          |
| **Processing Delay**      | The amount of time (in seconds) by which the processing of files placed in the **Transactions** tab is delayed. This is a legacy setting. Best practice is to [use a File connector](../flows/designing-a-flow#interacting-with-the-local-file-system) to manage local file systems instead of this setting. |
| **Use ETag**              | Servers might include a checksum of the RSS content as the ETag (entity tag). Enable this setting to have the connector include the ETag from the previous response as the If-None-Match header in the outgoing request.                                                                                     |

## Establishing a Connection

A valid target **Feed URL** is required to establish a connection to any RSS service. Some services might also require authentication or a set of custom headers in order to consume the service.

The connector silently supports both HTTP and HTTPS target URLs. If the target URL is an HTTPS URL, set the **TLS Server Certificate** to the public key certificate identifying the server. To implicitly trust the target endpoint, set the field to `Any Certificate`.

### Authentication

The RSS connector supports HTTP authentication in the following formats:

* Basic (plain text)
* Digest (encrypted)
* NTLM
* Negotiate
* Proprietary

The connector provides the credentials specified in **Username** and **Password** with each request to the remote RSS service.
