WebDAV connectors support uploading resources to and downloading resources from an HTTP server.
Key Capabilities
- HTTP-based file transfer with multiple authentication schemes (None, Basic, Digest, NTLM, and Negotiate)
- Bidirectional file synchronization with remote folder polling and file mask filtering
- TLS client authentication and proxy support for secure connections
- Optional caching to ensure only new or updated files are downloaded
Overview
Each WebDAV connector is configured with an upload path and download paths on the remote server. Files processed by the connector are automatically uploaded to the specified upload path, and the download paths are polled for resources to retrieve.
Connector Configuration
This section contains all of the configurable connector properties.
Settings Tab
Authorization
Settings related to authenticating with the remote connection target.
| 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. |
| URL | The URL of the remote HTTP server host. |
| Auth Scheme | The authentication scheme to use for the connection. Options are None, Basic (the default option), Digest, NTLM, Negotiate, and Proprietary. |
| User Name | The username credential for authenticating with the server. |
| Password | The password credential for authenticating with the server. |
| Authorization Token | The token required for authorization when Auth Scheme is set to Proprietary. |
Server Authentication
Settings related to authenticating the identity of a TLS/SSL server.
| Setting | Description |
|---|
| Server Public Certificate | The public key certificate used to verify the identity of a TLS/SSL server. This is only necessary if the server requires a specific certificate for validation. If the server does not provide a TLS server certificate, you can leave this setting blank to allow the underlying OS/JVM to perform certificate validation, or set it to Any Certificate to unconditionally trust the target server’s identity. |
Send
Settings related to uploading files to the remote server.
| Setting | Description |
|---|
| Remote Folder | Files processed by the connector are uploaded to this folder. |
| Overwrite Action | Whether to overwrite or skip existing files. |
Receive
Settings related to downloading resources from the remote server.
| Setting | Description |
|---|
| Remote Folder | The folder on the remote server that is polled for files to download. Use a comma-delimited list to specify multiple paths. |
| File Mask | A glob pattern that determines which files within the Remote Path should be downloaded (for example, *.txt). |
| Delete | Check this to delete successfully downloaded files from the remote storage. |
Caching
Settings related to caching and comparing files between multiple downloads.
| Setting | Description |
|---|
| File Size Comparison | Check this to keep a record of downloaded file names and sizes. Previously downloaded files are skipped unless the file size is different than the last download. |
| Timestamp Comparison | Check this to keep a record of downloaded file names and last-modified timestamps. Previously downloaded files are skipped unless the timestamp is different than the last download. |
When you enable caching, the file names are case-insensitive. For example, the connector cannot distinguish between TEST.TXT and test.txt.
Advanced Tab
TLS Client Authentication
Settings related to client authentication when two-way TLS authentication is required.
| Setting | Description |
|---|
| Client Certificate | The private certificate presented during TLS client authentication. |
| Client Certificate Password | The password required to access the TLS client certificate. |
Advanced Settings
Settings not included in the previous categories.
| Setting | Description |
|---|
| Excluded Extensions | A comma-delimited list of file extensions that should not be processed by the connector. |
| Temp Upload Extension | A temporary extension to append to file uploads. After the upload completes, the file is renamed to its file name. |
| Recurse | Whether to download files in subfolders of the target remote path. |
| Timeout | The length of time (in seconds) the server waits for a connection response before throwing a timeout error. |
| Local File Scheme | A scheme for assigning filenames to messages that are output by the connector. You can use macros in your filenames dynamically to include information such as identifiers and timestamps. For more information, see Macros. |
| 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 to manage local file systems instead of this setting. |
Proxy Settings
Message
Logging
Miscellaneous
Automation Tab
Automation Settings
Settings related to the automatic processing of files by the connector.
| Setting | Description |
|---|
| Send | Whether files arriving at the connector are automatically uploaded. |
| Retry Interval | The amount of time before a failed upload is retried. |
| Max Attempts | The maximum number of times the connector processes the input file. Success is measured based on a successful server acknowledgement. If you set this to 0, the connector retries the file indefinitely. |
| Receive | Whether the connector should automatically poll the HTTP server for files to download. |
| Interval | The interval between automatic download attempts. |
| Minutes Past the Hour | The minutes offset for an hourly schedule. Only applicable when the interval setting above is set to Hourly. For example, if this value is set to 5, the automation service downloads at 1:05, 2:05, 3:05, etc. |
| Time | The time of day that the attempt should occur. Only applicable when the interval setting above is set to Daily, Weekly, or Monthly. |
| Day | The day on which the attempt should occur. Only applicable when the interval setting above is set to Weekly or Monthly. |
| Minutes | The number of minutes to wait before attempting the download. Only applicable when the interval setting above is set to Minute. |
| Cron Expression | A five-position string representing a cron expression that determines when the attempt should occur. Only applicable when the interval setting above is set to Advanced. |
Alerts Tab
SLAs Tab
Establishing a Connection
To establish a connection, the WebDAV connector requires the URL of the target HTTP server and any authentication credentials required by the server.
Set the Auth Scheme property to your authentication mechanism, and the Settings tab automatically updates with the appropriate set of credentials to enter.
Uploading and Downloading
Upload
To upload files, set the Remote Folder in the Send portion of the Settings page to the path on the remote HTTP server where files should be uploaded.
Use the Overwrite remote files option to indicate whether files that already exist on the server should be overwritten or skipped.
After configuration is complete, files placed in the connector Transactions tab are uploaded to the HTTP server. If Send Automation is enabled, the upload happens automatically; otherwise, you can send individual files from the Transactions tab.
If a file fails to upload, the application attempts to send it again after the Retry Interval has elapsed. This process continues until the Max Attempts has been reached, after which the connector raises an error.
Download
To download files, set the Remote Folder in the Receive portion of the Settings page to the path on the remote HTTP server from where files should be downloaded. Use a comma-delimited list to specify multiple folders.
Use the File Mask to set a glob filter (for example *.txt) that limits the downloads to files matching the filter.
Use Delete to specify whether successfully downloaded files should be removed from the remote storage.
