One VS multiple languages

Is there a fix for a single virtual server with multiple languages, UTF8 and Win-1252 for example?

  • What problem are you looking to solve? Are you trying to detect the client browser's language and redirect it to different backend servers? Are you using APM and want different languages on the logon page? Something else?

  • Yes APM is being used, and there are 2 different languages on various URIs. 

  •  It looks to be mainly blocking on certain characters input as win-1252, for example, %92.

      Regarding "blocking on certain characters": Can you describe the situation in a way that would allow me to reproduce the problem you're experiencing in a quick lab test?

       

       

    • Metacharacter checks seems more like F5 AWAF/ASM thing than APM. The F5 WAF policy can be attached to specific urls using irule or local traffic policy, so you can 2 policies one for one language and another for the other language.
