irule stream::exporession and data group list

Hello,

 

 

I would like to rewrite responses from webservers to add a part to the url (in certain cases). Is it possible to use the stream::expression with data group lists? Like that, I could make a list for the source, and one for the target. The content of those lists would include things like

 

href="/asia/

 

so with only one double quote

 

 

If I just use a stream profile with those entries, it works. But the traget field would probably become too long if I had to put all strings in there.

 

 

I have tried something like

 

 

when HTTP_RESPONSE {

 

set stream_expression "@$::test_in@$::test_out@"

 

STREAM::expression $stream_expression

 

STREAM::enable

 

}

 

 

where test_in and test_out are data group lists

 

that does not work

 

 

any suggestions?
