HTTP host and uri, and if there's a match, rewrite uri and redirect to new host- works if refresh

[Nari]

Hi All,

Truley appricate your time ...

The below iRule works only if we referesh the brower multiple times, redirection happens but HTML delays to load the page

Requirment: Redirect old host to new host and replace the URI content and redirect

http://test.com/class/results.asp?subject=

This should be redirected

https://www.results.com/school/name?subject=

I have replace replaced the URI content and redirect new URI to new HOST, works only if we refresh the brower continueosly

when HTTP_REQUEST {
log local0. "[HTTP::host][HTTP::uri]"
if { [HTTP::host] equals "test.com" && [HTTP::uri] contains "class/results.asp?subject=" } {
log local0. "[HTTP::host][HTTP::uri]"
set current_uri [HTTP::uri]
set newuri [string map {class/results.asp? school/name?} [HTTP::uri]]
log local0. "https://www.results.com$newuri"
HTTP::redirect "https://www.results.com$newuri"
}
if { [HTTP::host] equals "test.com" && [HTTP::uri] eq "/class" || [HTTP::uri] eq "/class.subject.asp" } {
HTTP::redirect "https://www.results.com"
return
}
}

Not sure of what i am doing worng in this iRule. Please advice.

Thanks,

Hi, I hope you already found the answer, but if not, maybe this may help; 

In the IF statement, have you tried changing [HTTP::host] equals "test.com" to [HTTP::host] ends_with "test.com" ? 

Certain browsers and versions automatically add "www" to the beginning of the domain name, meaning it won't match the IF statements when you are using "equals".

Hope this helps.
