    Hi JD, 

    Thanks for posting this! 

    Have you tried storing the URL as a value?

    Doing something like this to capture the original url:

    if (req.restarts == 0) {
    set req.http.orig-url = req.url;
    }

    Then using that value in the flow. 


    The flow would look something like this:

    1. Original request comes in
    2. URL for request is stored in a value. (see above)
    3. Request gets sent to origin.
    4. 404 is returned from origin.
    5. req.url is rewritten to be like req.url = "/my404page"
    6. restart; is called.
    7. The request, now with req.url = "/my404page", goes to the origin, appropriate content is returned, and the content is served to the user with status 404.
    8. Previously set value is called 
    9. vcl_log is called and req.http.orig-url is logged.

    Let us know if you have any questions!

    Thank you, Dara, this looks really useful!  I've tested it in one of our services, and it looks like it does exactly what I need; the only other change that has to be made is to explicitly log "req.http.orig-url" instead of the default req.url.
