The proxy is currently registering a 502 Bad Gateway error. Is a failure to reach the internal server the most likely cause, or are there issues with communication between Apache 2.0.59 and IIS 6 which can cause this to occur? For example, attempting to access the default page would get you the error: Directory Listing Denied This Virtual Directory does not allow contents to be listed. Would such errors be directly relayed to the client?

I forgot that when we upgraded Apache we used the new config locations but didn't delete the old configs "just in case". The proxy element is now working alas I have a new and exciting problem, but it's one outside the scope of this list so thanks for your assistance. With time I hope I'll be more confident in my own diagnosis of the problem :) One question, when acting as a reverse proxy what does Apache use as a source port, anything above 1023? Paul Cocker IT Systems Administrator IT Security Officer 01628 81(6647) TNT Post 1 Globeside Business Park Fieldhouse Lane Marlow Bucks SL7 1HY Yup, apache just uses a free, non-privileged port. -- http://www.victortrac.com TNT Post is the trading name for TNT Post UK Ltd (company number: 04417047), TNT Post (Doordrop Media) Ltd (00613278), TNT Post Scotland Ltd (05695897),TNT Post North Ltd (05701709) and TNT Post South West Ltd (05983401).
