iRule redirect based on hostname

You can use a switch statement to avoid setting the HTTP::path value to lowercase twice:

when HTTP_REQUEST {
    if {[string tolower [HTTP::host]] equals "one.abc.com"}{
        switch [string tolower [HTTP::path]] {
            "/sites/hr" -
            "/pages/aboutme.aspx" {
                 Do nothing and allow request to go to virtual server default pool
            }
            default {
                 For all other requests, redirect to new URL
                HTTP::redirect "http://one.xyz.com/sites/sync/SitePages/Home.aspx"
            }
        }
    }
}

Brad - that worked, thanks so much for the help!!

Cory - I haven't done much with local traffic policies but I'll take a look at that for any future requests.

Brad - one more request if you don't mind.

Can you help me with the syntax to to add the following 2 additional sites to the iRule? Basically, don't redirect for these additional 2 sites:

http://one.abc.com/pub/ http://one.abc.com/sites/sa

I'm using this iRule:

when HTTP_REQUEST { if {[string tolower [HTTP::host]] equals "one.abc.com"}{ if {not (([string tolower [HTTP::path]] starts_with "/sites/hr") || ([string tolower [HTTP::path]] equals "/pages/aboutme.aspx"))}{ HTTP::redirect "; } } }

So the best ways to accomplish this is to either use a variant of Hoolio's suggestion of using a switch like this:

when HTTP_REQUEST {
    if {[string tolower [HTTP::host]] equals "one.abc.com"}{
        switch -glob [string tolower [HTTP::path]] {
            "/sites/hr/*" -
            "/pages/aboutme.aspx" -
            "/pub/*" -
            "/sites/sa/*" {
                 Do nothing and allow request to go to virtual server default pool
            }
            default {
                 For all other requests, redirect to new URL
                HTTP::redirect "http://one.xyz.com/sites/sync/SitePages/Home.aspx"
            }
        }
    }
}

Or if you plan to add additional URLs in the future the use of a data group would probably be better so you don't have to edit the rule, just add entries to your data group:

when HTTP_REQUEST {
    if {[string tolower [http::host]] equals "one.abc.com"}{
        if{not ([class match [string tolower [HTTP::path]] starts_with "/Common/dont_redirect_dg"])}{
            HTTP::redirect "http://one.xyz.com/sites/sync/SitePages/Home.aspx"
        }
    }
}
