Can I get the user's client proxy setting using 'REQUEST' or some other syntax, product, or utility. This is not Proxy Roles or ProxyPass, but the client's proxy settings if any. I am working on a help page to debug a user's settings if he or she can't get to certain pages with our proxy server settings on their browser. I am not sure, I understand what you want to know.

I you mean: how is the browser's proxie configuration: manually, direct connection or automatic (with what configuration file). Then, I fear, you will not get this information. If you want to know, which proxie was used for a given request, then there is some chance. Some proxies set the HTTP "VIA" header. Inside Zope, you access it as "HTTP_VIA". It can tell you through which proxies the request was routed. Dieter
