Posted by ddesmidt I let you read the example “Transparently convert an HTTP web application to HTTPS” under “Flexibility” on the aFleX example page:http://www.a10networks.com/vadc/index.php/aflex-examples/ Now to reply to your question, here is the same aFleX with a variable defined at the beginning: Code: when RULE_INIT { ################################## # Enter your domain set ::domain www.example.com ################################## } when HTTP_REQUEST { # Force servers to not reply with compression (compression can be enabled on the AX) HTTP::header remove Accept-Encoding } when HTTP_RESPONSE { # Test if the servers are sending a redirect and if so rewrite the redirect with https if { [HTTP::header exists "Location"]} { if {([HTTP::header "Location"] starts_with "http://$::domain")} { regsub "http://$::domain" [HTTP::header Location] "https://$::domain" new_location HTTP::header replace Location $new_location } } # Collect http response if the response time is text based to rewrite absolute links if { [HTTP::header "Content-Type"] starts_with "text" } { HTTP::collect } } when HTTP_RESPONSE_DATA { # Rewrite absolute links from http://$::domain/* to https://$::domain/* set payload_length [HTTP::payload length] regsub -all "http://$::domain" [HTTP::payload] "https://$::domain" new_payload HTTP::payload replace 0 $payload_length $new_payload HTTP::release }
