Is there a way to check if a browser accepts cookies without doing a redirect? I'm trying to fix a problem in the AD Provider where if a user has cookies turned off DNN goes into an infinite loop. Everything I've read/tried wants to use a redirect but so far if I try to use one when the AD Provider is initialized throws an error into the logs.

I'll keep hunting Cathal, thanks. I've seen other post in the AD forums before about the problem but it never clicked what it was until I was doing some live testing with the next version of the AD provider and we saw our logs just getting hammered. One or two people with cookies turned off can easily at an extra 50MB to a log file and I'm under fire from my boss because of it.
