Question

I would like to know what Poco classes to use in listening for a browser request. This is for a proxy server.
In general I want to open a port and wait for a request from a browser.
Please give an example as I’m quite new to Poco and C++ in general.

You can look at the HTTPTimeServer (http://pocoproject.org/docs/00100-GuidedTour.html#4) example. Basically you need:

• Poco::Util::ServerApplication. You derive from this class to host
  the server process.
• Poco::Net::ServerSocket to handle the
  socket to listen at.
• Poco::Net::HTTPServer which is in
  charge of accepting connections and
  dispatching them to
  HTTPRequestHandler derived instances.
• Poco::Net::HTTPServerParams that tell
  the server the number of threads and
  the size of the connection backlog.
• Poco::Net::HTTPRequestHandler. You
  derive from this class to handle
  requests.
• Poco::Net::HTTPRequestHandlerFactory.
  You derive from this class to create
  handler instances.
• Poco::Net::HTTPServerRequest which
  contains the information in the
  request (i.e. headers, body, cookies,
  authentication).
• Poco::Net::HTTPServerResponse. You
  populate an instance of this class
  with response information such as
  headers and body.
