irule help based on uri

Hi, ive done some searching on here but cannot find the exact help i need. We have the following scenario, can someone assist with an irule that will achieve this please?

we have one VIP that hostname site.abc.com resolves to, if user visits https://site.abc.com/live it should redirect to pool “pool_live” maintaining the uri “/live”. If user visits https://site.abc.com/test it should redirect to pool “pool_test” again maintaining the uri.

how can we achieve this?

thanks in advance!

Hi

You could do something like

when HTTP_REQUEST {
	if {[HTTP::uri] starts_with "/live"}{
		pool pool_live
	} elseif {[HTTP::uri] starts_with "/test"}{
		pool pool_test
	}
}

Another way would be with a Local Traffic Policy instead of an iRule. Under Local Traffic > Policies > Policy List, create a new policy. You’d need a rule in the policy like this for the first request:

image_240797.jpg
image_240797.jpg991×255 28.5 KB

The rule for the second URI would be built the same way. Then apply the policy to the VIP.

Im sorry to move the goalposts but my brief has changed to the following now:

we have one VIP that hostname site.abc.com resolves to, if user visits https://site.abc.com/live it should redirect to pool “pool_live” changing the ur toi “/live_site”. If user visits https://site.abc.com/test it should redirect to pool “pool_test” changing the uri to /test_site.

Is this achievable?

Hi cymru81,

iRule:

when HTTP_REQUEST {
	if { [string tolower [HTTP::host]] equals "site.abc.com" } {
		switch -glob [string tolower [HTTP::uri]] {
			"/live" {
				HTTP::uri "/live_site"
				pool pool_live
			}
			"/test" {
				HTTP::uri "/test_site"
				pool pool_test
			}
		}
	}
}

iRule with redirect:

when HTTP_REQUEST {
	if { [string tolower [HTTP::host]] equals "site.abc.com" } {
		switch -glob [string tolower [HTTP::uri]] {
			"/live" {
				HTTP::redirect "https://site.abc.com/live_site"
				pool pool_live
			}
			"/test" {
				HTTP::redirect "https://site.abc.com/test_site"
				pool pool_test
			}
		}
	}
}

If the HTTP::host is not site.abc.com, you can reject requests.

thank you the first rule is just the job!

ive got another issue now, it works as expected so if a user goes to https://site.abc.com/live they end up at https://site.abc.com/live\_site but if they try to navigate any subsequent links it fails.

Basically we have an external url https://site.abc.com/live\_site/ that we want a proxy mapping that will go to http://internalserver:1234/live - we have a pool “pool_live” that contains “internalserver:1234”.

is this totally achievable or am i missing something fundamental!

Hi

To keep the rest of the path in place, use something like this. This will replace /live with /live_site and then remove the first 5 characters from the uri (so /live) and then insert the rest of the path

when HTTP_REQUEST {
	if {[HTTP::uri] starts_with "/live"}{
		HTTP::uri /live_site[string range [HTTP::uri] 5 end]
		pool pool_live
	} elseif {[HTTP::uri] starts_with "/test"}{
		HTTP::uri /test_site[string range [HTTP::uri] 5 end]
		pool pool_test
	}
}

thank you once again! ive managed to get this working now with a local traffic policy and a rewrite profile, think some luck involved too!
