I have an issue with my ASM, i am not able to open a pdf file when using F5 under F5 even if is legal request :
Please, any idea about this issue ?
in my case
abnomal http protocol.
if you can check the content length, Because Web Firewall solutions view content sizes, signatures are detected when data sizes are different.
Hi @Hooni_L ,
Please note that i have fotgate FW, and test is done without F5.
So FW has not impact.
Hi @Hamza ,
Try to disable ASM policy first from your Virtual server and see if this fixed this issue or not ,
-if yes you should see what makes ASM to block opening or downloading PDF files requests ,
-If not you should disable http profile from your virtual server and change virtual server type from standard to performance layer 4 " If this available with you and this web site does not serve production services now " , if this issue resolved , I recommend to disable http parsing against PDF files as clarified in the below KB :
but first differentiate if this an ASM issue or not.
I hope this helps you
For ASM I am using the policy with transparent mode.
For http profile, i have already applicate the irule mentioned in the below KB :
