Hi,
when HTTP_REQUEST { if { [string tolower [HTTP::host]] equals "abc-test-domain.com" } { HTTP::respond 301 "Location" "http://dc-abc-test-domain1.com" } }
Abhijith_SubbanIf, the listening and responding port is 8080 then during http response header. Can this be done :
when HTTP_REQUEST { if { [string tolower [HTTP::host]] equals "abc-test-domain.com" } { HTTP::respond 301 "Location" "[http://dc-test-domain1.com:8080 :8080"](http://dc-test-domain1.com:8080 :8080); } }

Yes, sure.
THiJust a note on the 301 redirect:
Instead of 301 Moved Permanently, I'd rather use 307 Temporary Redirect. Browsers may cache 301s indefinitely, and it may be difficult to remove the cache entry, if you need to modify the redirect location later on. Depending on browser, the 301 cache may persist over restarts..
Some may use 302 redirects, but 307 will also keep the original HTTP method (eg. GET, POST, HEAD), 302 may not.
So, I would try to avoid a 301 redirects, unless I were 100% sure of the need of permanently de-commissioning the old URL.
