Search and Replace with iRule

OK,

 

 

I have looked into this again and found that using Stream might be the best option, so what I have so far is:

 

 

when HTTP_RESPONSE {

 

 

Disable the stream filter by default

 

STREAM::disable

 

 

Check if response type is text

 

if {[HTTP::header value Content-Type] contains "text" and [HTTP::header "User-Agent"] contains "***"}{

 

 

Replace

 

STREAM::expression "@123@xyz@ @456@xyz@"

 

 

Enable the stream filter for this response only

 

STREAM::enable

 

}

 

}

 

 

However I also need to check the uri as I only want to replace on certain areas. How can I do this? Can I use HTTP_REQUEST with the HTTP_RESPONSE?
