ASM - Profile XML and Parameter delimiter

Hello,

 

We have a VS (https) that is redirecting to a server hosting WSDL services (http:7777). Using a stream profile, we are rewriting the wsdl file content responded by the server so the client correctly goes through the F5 instead of the server directly. This works fine.

 

We have an ASM profile on this VS, with a XML Profile.

 

For some reason, it looks like the ASM does not reconigze XML data. For example, an illegal parameter value length is triggered by this (I manually truncated the request):

 

http://schemas.xmlsoap.orgxxxxx"; xmlns:u=";blablablabla

 

The system identify

 

1) Why is the system not recognizing XML data ? 2) What are the parameter delimiter ? Any way of changing them ?
