Redirect requests of all URLs except few URLs

Dear Beloved Community,

I have a requirement to fulfill in LTM as below for which I need your support to provide me an iRule.

 

Client requests containing any URIs should be redirected as below

https://abc.com redirect to https://xyz.com

 

But If client requests contains any of following URIs then do not perform redirection to https://xyz.com

https://abc.com/morning

OR

https://abc.com/afternoon

OR

https://abc.com/night

OR

https://abc.com/school

OR

https://abc.com/leadership

 

Your Sincerely

    Hi,

    when HTTP_REQUEST {
	if { [HTTP::host] equals "abc.com" } {
		switch [string tolower [HTTP::uri]] {
			"/morning" -
			"/afternoon" -
			"/night" -
			"/school" -
			"/leadership" { }
			default {
				HTTP::redirect https://xyz.com[HTTP::uri]
				return
			}
		}
	}
}

    Hi Enes,

    Thank you for your input.

     

    I have tested this iRule but all the URLs including "/morning" , "/afternoon" , "/night" , "/school" , "/leadership" are being redirected while the requirement is few URLs should not redirect and the remaining all other should redirect.

    Do the urls start with "/morning", "/afternoon", "/night", "/school", "/leadership" or are they exactly equals?

    when HTTP_REQUEST {
	if { [HTTP::host] equals "abc.com" } {
		switch -glob [string tolower [HTTP::uri]] {
			"/morning*" -
			"/afternoon*" -
			"/night*" -
			"/school*" -
			"/leadership*" {
				log local0. "not redirect - uri: [HTTP::uri]"
			}
			default {
				log local0. "redirect - uri: [HTTP::uri]"
				HTTP::redirect https://xyz.com[HTTP::uri]
				return
			}
		}
	}
}

    Can you investigate the ltm logs?

      The URLs are exactly same. So I am still using the first iRule, which you provided. Any idea how we can fix it. I am searching LTM logs in GUI by filtering logs with VS name but no logs are appearing.

        when HTTP_REQUEST {
	log local0. "vs: [virtual name] uri: [HTTP::uri] host: [HTTP::host]"
	
	if { [HTTP::host] equals "abc.com" } {
		switch [string tolower [HTTP::uri]] {
			"/morning" -
			"/afternoon" -
			"/night" -
			"/school" -
			"/leadership" {
				log local0. "not redirect - vs: [virtual name] uri: [HTTP::uri]"
			}
			default {
				log local0. "redirect - vs: [virtual name] uri: [HTTP::uri]"
				HTTP::redirect https://xyz.com[HTTP::uri]
				return
			}
		}
	}
}

        You can use the following command to filtering.

        tail -f /var/log/ltm | grep irulename
