Greetings:
We have an email article pop-up with a captcha that works, when hit directly on a relatively slow IIS7 backend, since it has "time" to generate and get served as part of the pop-up. I observe that when we accelerate with varnish, the pop-up loads too quickly, and the captcha image is not built in time, so varnish serves a 404 to the client, and the image is not there. Upon refresh it has been built and gets served. I am using client director and pipe (necessarily) to ensure we hit the same backend for the correct captcha and corresponding transactions. Is an individual 404 something to which we can introduce a small delay, or a restart? Can we potentially build a delay into vcl for the individual captcha requests to compensate for this slowness since these are not cacheable? Has anyone implemented a "patience" subroutine?
