Old URL 404, compare URI with external data group file

Thanks for the reply, we understand your reply but not sure how to finish the last part of this.

when HTTP_REQUEST {

setting a variable for the URI

set uri [HTTP::uri]

setting a variable for the external string data group

set v3 $::v3redirects

finds the text after the last / in the URL

string range $uri [expr {[string last / $uri] + 1}] end

}

if 404 and URI matches our external data group

if HTTP_RESPONSE { [HTTP::status] == 404} and { [matchclass $uri equals $v3] }

I think the above is almost correct, what we are stuck ont is if there is a $uri match extract the whole URL from the data group into another variable

Once we have a variable we can then do a 301 redirect to.

Another question, what happens if there is no match ? will you get a 404 or should we handle it with an else statement to our home page for example ?

thanks in advance
