Issue in Downloading Files (pdf/xls/jpeg) with ASM Policy and http profile enabled


Hello Everyone,


I have an environment in which I have enabled ASM Policy and is in blocking mode. The HTTP Profile is also enabled.

I am getting 'Failed-Network Error' while downloading files and LTM logs shows me this error


Jan 8 10:53:38 err tmm3[20410]: 011f0016:3: http_process_state_prepend - Invalid action:0x10a010 Server sends too much data. serverside clientside (Server side: vip=/Common/profile=http pool=/Common/)


I have tried so many solutions given on different forums, but could not get through this. Some suggest to disable http and ASM for particular URI, upon doing which, the webpage stops loading.


Kindly help.




The virtual server is configured with an HTTP profile, and the BIG-IP system receives a response from the pool member that either contains more data than indicated in the Content-Length header or has additional data following the ending chunk of a chunked response.
