Upload documents via slow connection

HI,

we've got a problem with upload of documents from client via slow connection since we migrated to F5. Now when client uploads document, traffic is send directly to back end and it time out. Before we were using Apache with weblogic plugin http://docs.oracle.com/cd/E13222_01/wls/docs81/plugins/plugin_params.html ,where FileCaching parameter says: When set to ON, and the size of the POST data in a request is greater than 2048 bytes, the POST data is first read into a temporary file on disk and then forwarded to the WebLogic Server in chunks of 8192 bytes.

Is it any possibility how to do it at F5?? Thanks
