Once a request is received by a server and parsed sufficiently to determine its target URI, the server decides whether to process the request itself, forward the request to another server, redirect the client to a different resource, respond with an error, or drop the connection. This decision can be influenced by anything about the request or connection context, but is specifically directed at whether the server has been configured to process requests for that target URI and whether the connection context is appropriate for that request.<\/p>\n

Since the host and port information acts as an application-level routing mechanism, it is a frequent target for malware seeking to poison a shared cache or redirect a request to an unintended server. An interception proxy is particularly vulnerable if it relies on the host and port information for redirecting requests to internal servers, or for use as a cache key in a shared cache, without first verifying that the intercepted connection is targeting a valid IP address for that host.<\/p>\n
