    I somehow got it to work with this solution (not sure why it wasn't working before)

    amp;[a-zA-Z0-9]*

Hello,

 

Thank you for your answer.

I tried it and it still doesn't work.

Anyway there is the posibility that the parameters in the request will be amp;Arg02 or amp;arg100 or even amp;Opt10

The regex in my opinnion should match any parameter that starts with this string amp; and then anything else untill the = sign

I also tried it on the regex website and even on the f5 regex tester and the regex appears to be ok but when I try to use it in the policy it fails
