APM URL Branching tolower

Hello Folks,

 

Situation is: I've a Per-Request-Policy with URL Branching for specific URL to activate a 2 FA. 

-> this is working.

 

Problem: URL Branching is only working with a exact matching URI's => case sensitive

e.g. URL Branch: /path/path123

      -> incoming request -> /path/path123/ -> 2FA working

      -> incoming request -> /path/Path123/ -> 2FA is bypassed

 

Is there any possibility in APM to change all incoming requests to lower case with an in-build-function (only for URL Branch checking)?

 

Current workaround would be an iRule to convert all URI's to lower case. I have no idea whether this is always a good idea (maybe the backend can't handle case - insensitive paths).

 

 

Thanks a lot.

R.

    So in your URL Branching now you have a branch like "Expression: URL contains: /path/path123/"

    Which if you go to Advanced is actually "expr {[mcget {perflow.branching.url}] contains "/path/path123/"}"

    You then could try "expr {[string tolower [mcget {perflow.branching.url}] contains "/path/path123/"]}"

      Thanks. Working perfect.

       

      correct syntax

        expr {[string tolower [mcget {perflow.branching.url}]] contains "/path/path123/"}
