Class HTTPRequestFilter

java.lang.Object

net.grinder.plugin.http.tcpproxyfilter.HTTPRequestFilter

All Implemented Interfaces:

TCPProxyFilter

public final class HTTPRequestFilter
extends Object
implements TCPProxyFilter

TCPProxyFilter that transforms an HTTP request stream into an XML document.

Bugs:

• Assumes Request-Line (GET ...) is first line of packet, and that every packet that starts with such a line is the start of a request.
• Should filter chunked transfer coding from POST data.
• Doesn't handle line continuations.
• Doesn't parse correctly if lines are broken across message fragments.
