Hi Mary,

you may try the iRule and external data-group below (or at least take a look at it :)...

when HTTP_REQUEST {
    if { [set location [class match -value [string tolower "[HTTP::host][HTTP::uri]"] starts_with DG_MyRedirects]] ne "" } then {
        HTTP::redirect $location    
    }
}

External data-group structure:

"input_url" := "target_url",
"publications.mcgill.ca/mcgillnews/2015/10/09/the-myths-around-not-criminally-responsible" := "http://mcgillnews.mcgill.ca/s/1762/news/interior.aspx?sid=1762&gid=2&pgid=572",
"publications.mcgill.ca/somepath" := "http://mcgillnews.mcgill.ca/page.aspx?path=somepath",
"publications.mcgill.ca/somepath/somepath" := "http://mcgillnews.mcgill.ca/page.aspx?path=somepath%2Fsomepath",

Note: The ordering of the data-group does not matter, the

[class]

command will always pick the best-matching entry and use the "target_url" data for the redirect. Also keep in mind that the outlined iRule uses a
starts_with
operator, so that you can redirect every request underneath a given URL structure to the new URL.
