    I ve done the server but I need to answer the optional questions ( it is only 2 questions)Currently, the web server handles only one HTTP request at a time. Implement a multithreaded server that is capable of serving multiple requests simultaneously. Using threading, first create a main thread in which your modified server listens for clients at a fixed port. When it receives a TCP connection request from a client, it will set up the TCP connection through another port and services the client request in a separate thread. There will be a separate TCP connection in a separate thread for each request/response pair. 2. Instead of using a browser, write your own HTTP client to test your server. Your client will connect to the server using a TCP connection, send an HTTP request to the server, and display the server response as an output. You can assume that the HTTP request sent is a GET method. The client should take command line arguments specifying the server IP address or host name, the port at which the server is listening, and the path at which the requested object is stored at the server. The following is an input command format to run the client. server_host server_port filename

Verifying Implementation of UML Sequence Diagrams Using Java PathFinder


The introduction of combined fragments to UML 2.x sequence diagrams makes it much harder for programmers to check manually the correctness of an implementation, especially when the fragments are nested. We develop an extension for Symbolic Java Path Finder (SPF) to verify if a Java program correctly implements its sequence diagram specification. Our main contribution is an algorithm to follow SPF exploration both when it advances and when it backtracks to find execution paths that are not specified in the s
