### File Transport Configuration page (Proxy Services)

Use this page to configure transport settings for a proxy service using the file transport protocol.

Option | To create or edit...
--- | ---
File Mask | Enter the regular expression for the files to be picked. The default is `*.*`.
Managed Server | Select the Managed Server for polling in a clustered domain. This field is available only in a clustered domain.
Polling Interval | Enter a polling interval, in seconds. The default is `60`.
Read Limit | Specify the maximum number of messages to read per polling sweep. Enter `0` to specify no limit. The default is 10.
Sort By Arrival | Select this check box to specify that events are delivered in the order of arrival. Note that when this option is selected for a proxy service that is executed in a clustered environment, messages are always sent to the same server. In other words, load balancing across servers is ignored when this option is selected.
Scan Subdirectories | Select this check box to recursively scan all the directories.
Pass By Reference | Select this check box to stage the file in the archive directory and pass it as a reference in the headers.
Post Read Action | Select what happens to a message after it has been read: Archive - The message is archived. Delete - The message is deleted.
Stage Directory | Enter an intermediate directory to temporarily stage the files while processing them. Do not put the stage directory inside of the polling directory (the directory identified in the URL of the file transport proxy service; for example, file:///c:/dir1/dir2).
Archive Directory | Specify the path to the archive location if the Post Read Action option is set to Archive. The Archive Directory field is also a required field if you have selected the Pass By Reference field. Do not put the archive directory inside of the polling directory.
Error Directory | Enter the location where messages and attachments are posted if there is a problem. Do not put the error directory inside of the polling directory.
Request Encoding | Accept the default `UTF-8` as the character set encoding for requests in file transports, or enter a different character set encoding.
