F5 Doesnt send POST request to ICAP

Hi All

 

I have a VS on F5 which is an SSL Offloading VS to begin with and then also acts as content switching VS by the virtue of an irule.

 

It also has some irules for basic stuff like Diable HTTP options in header and also redirect http to https ( well its not required but client has it there).

 

Now I can see the F5 is sending all traffic to ICAP but that one POST for file upload. Just sends it to backend server.

 

ICAP server here is Trend Micro

 

Anyone faced similar issue before?

 

We are v11.3.0 currently. Were on 11.6.1 and upgraded before I took up this issue.

 

Let me know if you need further details.
