Some servers may wish to simply refuse the connection. The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server specified by the URI (e.g. HTTP, FTP, LDAP) or some other auxiliary server (e.g. DNS) it needed to access in attempting to complete the request.

Upgrading to TLS Within HTTP/1.1 The CONNECT method was originally described in a Work in Progress titled, "Tunneling TCP based protocols through Web proxy servers", by Ari Luotonen of Netscape Communications Corporation. It was widely implemented by HTTP proxies, but was never made a part of any IETF Standards Track document. Hypertext Transfer Protocol -- HTTP/1.1 - World Wide Web The following references are informative: Luo1998 ("Tunneling TCP based protocols through Web proxy servers", also update reference to quote the expired Internet Draft properly). Nie1997 ("Network Performance Effects of HTTP/1.1, CSS1, and PNG"). Pad1995 ("Improving HTTP Latency"). RFC821 (SMTP), also update the reference to RFC2821.

Proxy Server uses reverse proxying and reverse hosting to send requests to Web publishing servers connected behind the Proxy Server computer. Now you can place your Web server behind the Proxy Server computer to publish to the World Wide Web without compromising the security of the Web server or its data.

The Design and Implementation of a SSL Proxy Compare the performance of SSL Proxy on Linux and IXP-12EB. 4. Implementation. HTTPS is very slow compared to HTTP, so designing and implementing an efficient proxy will be challenging. The proxy will be making routing decisions based on IP address, TCP port number, URL, HTTP Meta header, and value of XML tags. 5.Testing
