iRule for URI 'Percent encoding' doesn't work
Hi Guys,
We use different iRules in the same VS with the same event triggers. This should be possible in SW-Vers. 12.1.2.
The functions are different, of course.
So the 1st iRule is generally installed in many VSn and the 2nd iRule is specifically only for one VS.
the problem:
in an URI of an http-request are represented European ASCII special characters with "Percent-encoding" (e.g. '%C3%9F' for character 'ß' or '%C3%BC' for character 'ü').
For the correct translation of ASCII special characters in the URI we use the 2nd iRule. We want to use the 'URI :: decode' function for correction.
We have the following problem:
It seems as if the rule works fine and the function is executed (I see the processing run in the log-file) but the request to the poolmember transfers the original uri ( I see this in the tcpdump and in the server-log-file).
What could be the issue? What's wrong on the setting?
Any ideas everyone?
