WebDAV connectors support uploading resources to and downloading resources from an HTTP server.
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.
This section contains all of the configurable connector properties.
Settings related to authenticating with the remote connection target.
- 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.
Settings related to authenticating the identity of an SSL server.
- Server Public Certificate If the HTTP server uses HTTPS, set this field to the certificate that identifies the server. If the server’s certificate is not available, you can set this field to ‘Any Certificate’ to implicitly trust the server’s identity.
Settings related to uploading files to the remote server.
- Remote Folder Files processed by the connector are uploaded to this folder.
- Overwrite Whether to overwrite or skip existing files.
Settings related to downloading resources from the remote server.
- 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.
Settings related to caching and comparing files between multiple downloads.
- 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.
Settings related to the automatic processing of files by the connector.
- 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 connect retries the file indefinitely.
- Receive Whether the connector should automatically poll the HTTP server for files to download.
- Receive 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.
Settings related to the allocation of resources to the connector.
- Max Workers The maximum number of worker threads consumed from the threadpool to process files on this connector. If set, this overrides the default setting on the Settings > Automation page.
- Max Files The maximum number of files sent by each thread assigned to the connector. If set, this overrides the default setting on the Settings > Automation page.
TLS Client Authentication
Settings related to client authentication when two-way TLS authentication is required.
- Private Certificate The private certificate presented during TLS client authentication.
- Certificate Password The password required to access the TLS client certificate.
These are a collection of settings that identify and authenticate to the proxy through which the WebDAV connection should be routed. By default, this section uses the global settings on the Settings Page. Clear the checkbox to supply settings specific to your connector.
- Proxy Type The protocol used by a proxy-based firewall.
- Proxy Host The name or IP address of a proxy-based firewall.
- Proxy Port The TCP port for a proxy-based firewall.
- Proxy User The user name to use to authenticate with a proxy-based firewall.
- Proxy Password A password used to authenticate to a proxy-based firewall.
- Authentication Scheme Leave the default None or choose from one of the following authentication schemes: Basic, Digest, Proprietary, or NTLM.
Settings not included in the previous categories.
- Excluded Extensions A comma-delimited list of file extensions that should not be processed by the connector.
- Recurse Whether to download files in subfolders of the target remote path.
- Processing Delay The amount of time (in seconds) by which the processing of files placed in the Input folder is delayed. This is a legacy setting. Best practice is to use a File connector to manage local file systems instead of this setting.
- Timeout The length of time (in seconds) the server waits for a connection response before throwing a timeout error.
- Save to Sent Folder Check this to copy files processed by the connector to the Sent folder for the connector.
- Sent Folder Scheme Instructs the connector to group messages in the Sent folder according to the selected interval. For example, the Weekly option instructs the connector to create a new subfolder each week and store all messages for the week in that folder. The blank setting tells the connector to save all messages directly in the Sent folder. For connectors that process many messages, using subfolders helps keep messsages organized and improves performance.
- Log Level The verbosity of logs generated by the connector. When you request support, set this to Debug.
- Log Subfolder Scheme Instructs the connector to group files in the Logs folder according to the selected interval. For example, the Weekly option instructs the connector to create a new subfolder each week and store all logs for the week in that folder. The blank setting tells the connector to save all logs directly in the Logs folder. For connectors that process many transactions, using subfolders helps keep logs organized and improves performance.
- Log Messages Check this to have the log entry for a processed file include a copy of the file itself. If you disable this, you might not be able to download a copy of the file from the Input or Output tabs.
Miscellaneous settings are for specific use cases.
- Other Settings Enables you to configure hidden connector settings in a semicolon-separated list (for example,
setting1=value1;setting2=value2). Normal connector use cases and functionality should not require the use of these settings.
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
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 Input tab are uploaded to the HTTP server. If Send Automation is enabled, the upload happens automatically; otherwise, you can send individual files from the Input 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.
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.
