Rewriting a header inside RESPONSE_DATA

The problem I am having trouble over coming is that I am trying to find a way to basically do the equivalent of "s/http:\/\/server.:8080/https:\/\/bigtest1/" on the location header of the outgoing data. The Apache ProxyPassReverse function handled this for me, and now I need to find a way to duplicate this functionality.

 

 

Is there a way in iRules to do a search and replace of a header?

 

The only way I've found to do it is listed below, but it sucks when Error.jsp has a dynamically generated QUERY_STRING.

 

 

when HTTP_RESPONSE {

 

if { [HTTP::header location] starts_with "http://server1:8080/app/Error.jsp" } {

 

HTTP::header replace location https://bigtest1/app/Error.jsp

 

} elseif { [HTTP::header location] starts_with "http://server2:8080/app/Error.jsp" } {

 

HTTP::header replace location https://bigtest1/app/Error.jsp

 

}

 

}
