Need to redirect complete URL into redirected uri

Hello Everyone, 

I am looking for an iRule for redirection of below https://URL1 into another https://2URL/redirect?url=https://URL1

Example: 

Request:      https://www.abc.com/find/redirect   

Redirect:  http://www.xyz.com/found/redirect?url=https://www.abc.com/find/redirect

Example:  http://www.xyz.com/found/redirect?url=https%3A%2F%2Fabc.com%2Ffind%2Fredirect

Thanks in Advance:

    ashk If your intent is to redirect anything going to www.abc.com  with any URI path starting with "/find/redirect/" the following should work for you.

     

    when CLIENT_ACCEPTED priority 500 {

    set DEFAULT_POOL [LB::server pool]

}

when HTTP_REQUEST priority 500 {

    set HOST [string tolower [HTTP::host]]
    set URI [string tolower [HTTP::uri]]

    if { ${HOST} == "www.abc.com" } {
        if { ${URI} starts_with "/find/redirect/" } {
            
            HTTP::respond 301 Location "https://www.xyz.com/found/redirect?url=https://$HOST$URI"

        }
    } else {
        $DEFAULT_POOL
    }

}

     

    Now if you want to redirect anything that connects to www.abc.com  to www.xyz.com/found/redirect?url=https:// <old_path> the following should do the job.

     

    when CLIENT_ACCEPTED priority 500 {

    set DEFAULT_POOL [LB::server pool]

}

when HTTP_REQUEST priority 500 {

    set HOST [string tolower [HTTP::host]]
    set URI [string tolower [HTTP::uri]]

    if { ${HOST} == "www.abc.com" } {

        HTTP::respond 301 Location "https://www.xyz.com/found/redirect?url=https://$HOST$URI"

    } else {
        $DEFAULT_POOL
    }

}

     

    If I am missunderstanding the request please provide a real world example of one of the requests or rewording the question so we can have a different approach to the issue at hand.

    ashk I believe something like the following would work for you while also assuming your virtual server has a default pool associated to it and you are performing SSL termination on that virtual server.

    when CLIENT_ACCEPTED priority 500 {

    set DEFAULT_POOL [LB::server pool]

}

when HTTP_REQUEST priority 500 {

    set HOST [string tolower [HTTP::host]]
    set URI [string tolower [HTTP::uri]]

    if { ${HOST} == "www.abc.com" } {
        if { ${URI} == "/find/redirect" } {
            
            HTTP::respond 301 Location "https://www.xyz.com/found/redirect?url=https://$HOST$URI"

        }
    } else {
        $DEFAULT_POOL
    }

}

    Hello Paulius,

    Thank you for the rule, I see its working with the URI only when its "/find/redirect". 

    it is not working when I use "*"  if { ${URI} == "/find/redirect/*" } 

    i tried starts with but syntax error. How to ger all the query string in path which starts with /find/redirect/XXXX/xXXx/XXX/XX something like this.

    Appreciate your help.
