You can modify the REGEX experssion. Currently:

 STREAM::expression {@http://@https://@}

So, if you want to match only on FQDN www.mysite.com, this would be as follows:

 STREAM::expression {@http://www.mysite.com@https://www.mysite.com@}

Hope this helps? If not, please give examples of the transformation you are looking to accomplish. Initial URI and post URI.

as whisperer said that stream directive is regex, so:
 ":" and "." are part of regex syntaxes, so i suggest replace them with \x3A and \x2A
reference for the hexadecimal codes: https://man7.org/linux/man-pages/man7/ascii.7.html

To disable server side compression, simply apply HTTP compression profile to the virtual server.
this enables the compression offload which ltm requests uncompressed response from server (i.e. no Accept-Encoding header in server bound request).
