how to find/replace part of the url

[JJoe]

Don't use "URL:" when maintaining header filter order is necessary.
"URL:" match includes protocol.
$URL match includes protocol.
Add a domain match. Leading wildcards use more time.

Code:

[HTTP headers]
In = FALSE
Out = TRUE
Key = "! : JUMP: q=hello to q=hello&c=1 (out)"
URL = "*q=hello(^\&c=1)$URL(\1q=hello\2)$JUMP(\1q=hello&c=1\2)"

Code:

[HTTP headers]
In = FALSE
Out = TRUE
Key = "URL: Jump q=hello to q=hello&c=1 (out)"
Match = "\1q=hello(^\&c=1)\2"
Replace = "$JUMP(\1q=hello&c=1\2)"
