Route traffic based on use case

Is it possible to use iRule to route traffic to one pool when there is a file upload and other HTTP traffic to a default pool?

Hi WTW,

Is it possible to use iRule...

Everything is possible with iRules... 😉

To develop a tailordered iRule for your Web Application, you have to find out how the upload functionality is implemented. Some Web Application are using a HTTP-POST request targeting a specific file (e.g. 

./upload.php
) to upload the data and some others Web Applications are using the HTTP-PUT request (e.g. Webdav Clients).

Depending on your Web Application an iRule may look like this:

Example 1:

when HTTP_REQUEST { 
    if { [string tolower [HTTP::path]] ends_with "upload.php" } then {
        pool upload_pool
    } else {
        pool default_pool
    }
}

Example 2:

when HTTP_REQUEST { 
    if { [HTTP::method] equals "PUT" } then {
        pool upload_pool
    } else {
        pool default_pool
    }
}

Cheers, Kai
