How to write a iRule to check if the incoming HTTP header is "abc123" then add a header "efg123" in front of "abc123"?

CirrostratusHi there,
You can use HTTP::header (Click here) to check if a header exists and to insert a new header or modify a new header.
Do you want to check if the header name is abc123 or the header value is abc123? Does the order of the HTTP headers matter? By default if you insert a new header it will be inserted after the existing headers. If you need the new header inserted before the existing one, you could insert the new one, save the value of the old one, remove the old one and insert a new instance of the old header.
