Class HTTP

java.lang.Object
  org.xwt.HTTP

public class HTTP

extends java.lang.Object

This object encapsulates a *single* HTTP connection. Multiple requests may be pipelined over a connection (thread-safe), although any IOException encountered in a request will invalidate all later requests.

Nested Class Summary

class	HTTP.HTTPInputStream An input stream that represents a subset of a longer input stream.
static class	HTTP.Proxy encapsulates most of the proxy logic; some is shared in HTTP.java

Constructor Summary

HTTP(java.lang.String url)

HTTP(java.lang.String url, boolean skipResolveCheck)

Method Summary

java.net.Socket	attemptDirect() Attempts a direct connection
java.net.Socket	attemptHttpProxy(java.lang.String proxyHost, int proxyPort) Attempts to use an HTTP proxy, employing the CONNECT method if HTTPS is requested
java.net.Socket	attemptPAC(JS.Callable pacFunc) executes the PAC script and dispatches a call to one of the other attempt methods based on the result
java.net.Socket	attemptSocksProxy(java.lang.String proxyHost, int proxyPort) Implements SOCKSv4 with v4a DNS extension
java.io.InputStream	GET() Performs an HTTP GET request
java.io.InputStream	POST(java.lang.String contentType, java.lang.String content) Performs an HTTP POST request; content is appended to the headers (so it should include a blank line to delimit the beginning of the body)
void	sendRequest(java.lang.String contentType, java.lang.String content)
