Need help with URL re-write without a redirect

I have virtual server on F5 with an iRule and want to add a condition for a new re-write. I have to re-write complete URL without redirecting or changing the URL in client's browser. Tested the below...
application delivery
F5
LTM
rewrite
stream
url

    you would need to work with the application team to find out which URL's are returning 404 and reason for it. Modify your iRule accordingly to resolve it

It appears the rewrite is working as expected. Few suggestions, you don't need check for the HOST header again so can modify it as below.

 

} elseif {[string tolower [HTTP::uri]] eq "/uri/path"}
{ HTTP::header replace Host "abc4.domain4.com"
HTTP::uri "/file.html"
set doStream 4
log local0. "[HTTP::host][HTTP::uri] Changed rewrite"

 

Also, in the response modify as below

 

STREAM::expression {@https://abc4.domain4.com@https://abc.domain.com@}
STREAM::enable

 

Make sure your pool (test-pool) is up. Take a tcpdump capture and see the traffic and reason for the RST. Plase ask to check the logs from the server end as well.
