Hi,
I'm currently trying to add the ability to redirect requests for the initial
html page to a captcha page when there is no session or no valid session.
Currently I'm doing this in the fixups hook:
mod_smu_fixups(request_rec* r) {
....
}
So if we have an initial request that is HTML then redirect to captcha.shtml
which contains SSI for header, footer etc. There will also be a request for
a captcha image using a fixed filename. The fixup will detect this and send
the request to a custom handler that will auto-generate the captcha image.
The problem I have is that I'm getting sub-requests and requests for the
captcha image twice, see log below. I assume that the original request for
index.shtml and the request for captcha.shtml are being processed. Using
firebug I see that the captcha image that is displayed in the debug output
isn't the one that gets displayed in the HTML so I can assume that the image
is being sent twice. I notice that the browser goes into a waiting state
until the timeout expires. Does anybody know what I'm doing wrong? I've
tried returning DECLINED or DONE after the ap_internal_redirect_handler call
but still get the problem. Any help appreciated.
Best Regards,
Martin.
Try putting
if (!ap_is_initial_req(req))
return DECLINED;
at the beginning of your fixups callback.

I've Just got to the bottom of why I am receiving the captcha image
request twice. I had firebug turned on which was requesting the image
again although it didn't for all the other images on the page.
