I'm not sure about the way it works in AMosaic, but for releases of Mosaic for X Window version 2.7b1 and earlier this is how it works: Setting http_proxy tells the browser to send all URLs that start with "http" to a special proxy server that makes the URL requests on your behalf. So, in your example, all URL requests are sent to www.wupper.de:80. The server on www.wupper.de listening on port 80 then makes the URL request for you, and www.wupper.de sends that info back to you. Not all servers proxy support (or have it turned on), so you can't just put in any random httpd server to be the proxy. Unless CIS supports this somewhere (and I don't think they do), you can't use any CIS address to proxy info for you. AMosaic was originally based on XMosaic, so I'm pretty sure it works the same way. The next version of XMosaic gets rid of all this "http_proxy" stuff for proxies, and provides a nice user interface for setting all types of proxies, even generic proxies to let people experiment with writing new protocols. This next version may be released this Friday, if all goes well. Steve
