I've been itching to write a multi-node crawler for one of my projects, but haven't gotten around to it. The idea is to have multiple copies of the same program to distribute HTTP requests and submit all the data to one location.
Using a ServerSocket may or may not be a good way to do it. If you're using only one program (with, presumably, some built-in method of aggregating the data), you certainly could use a ServerSocket. If you've got multiple copies of application 'A' on multiple machines, and all of those report to a single instance of application 'B' on one machine, then 'B' would have a ServerSocket to which every 'A' would connect. At least for my uses, the latter would probably be a better implementation. 'A' would have only have to request data, parse as necessary, and submit to 'B'. In turn, 'B' would handle any number of requests from multiple 'A' instances. The former can pose a bit of a problem, though. Let's say you have three instances of 'A': A1, A2, and A3. Do you interconnect them (A1->A2, A1->A3, A2->A3)? If this is the case, then A2's ServerSocket has one connection (from A1), A3 has two (from A1 and A2), and A1 has none. You'd probably need an array of TCPSocket subclasses stored in an array that represents all outgoing connections. The ServerSocket would store all incoming connections. This would let you know exactly who is connected to your instance of 'A', though it's getting kind of ugly. Without knowing more about what you're trying to do, it's hard to say what a good solution is.
