问题 This is a rather convoluted question, and for that I apologize. I wrote a Linux C sockets application, a basic framework for a simplistic chat server. The server is running on my laptop. The client is Telnet at the moment until I write a designated client application (that'll be more secure, hopefully).

问题 The app I'm working on has a self contained database. The only time I need HTTP request is when the user first loads the app. I do this by calling a class that verifies whether or not a local DB exists and, if not, create one with the following request: HttpRequest data = new HttpRequest("http://www.somedomain.com/xml", "GET", this); data.start(); This xml returns a list of content, all of which have images that I want to fetch AFTER the original request is complete and stored.
