Enable compression of two or more adjacent slashes in a URI into a single slash.

Nginx has a merge_slashes module that will evaluate a URI like "/foo; and change it to "/foo/bar/foobar?slashes=many". But our IIS websites just display the browser URL the way the user input it: Our Google Analytics team sees these as unique pages in GA and want us to catch all adjacent slashes in a request and redirect it to the standard of one slash at a time. My irule tries have lead to redirect loops so I'm asking for someone's time and genius to help me out.

    You might be able to use something like this:

    when HTTP_REQUEST {
    if { [HTTP::uri] contains "//" } {
        set URIquals [split [HTTP::uri] "/"]
        set newURI ""
        foreach qual $URIquals {
            if { $qual ne "" } {
                append newURI "/" $qual
            }
        }
        HTTP::uri $newURI
    }
}

    I ran a small test using your input string above:

    Before URI: /foo

    After URI: /foo/bar/foobar?slashes=many
