Below is the source code, if you need a Class file that you need to package, please contact you: hcc4hcc@163.com (Note: Import in the program, there is no listing here) readme.txt ========== ======================================================================================================================================================================================================================================================================================= Speed, but not obvious; support breakpoint resume, support multi-thread download, but does not support IE breakpoint resume (not know why); currently testing on a FlashGet. 0.8 version update: Increase the thread pool; Class: WebserverLogger; optimize part of the code; add a custom log file name; increase the number of threads MAX and MIN in the custom thread pool; increase the number of customizable Size; (increasing the most important setting of download speed, recommended 128-256KB) increase timeout setting; (currently 5 seconds) Remove the bug found in the page (whose reason: It turned out to be two times in each thread () .: p); Fixed a format error in the HTTP protocol to correct the compatibility between the HTTP protocol and FlashGet, FlashGet can be downloaded normally (why: flashget establishes a socket connection with this server, no immediately Data, there is a short latency because this server has been optimized, and the response is very fast, and there is no timeout, so it is considered that the flashget is not connected, so it is cut off. Note: IE download and Netants have no problem.); Changed nearly 1/2 code. All Features: You can customize the listening port; you can customize whether the directory list is listed; you can customize the server name; you can customize the index file name; do not restart the server, change the parameter file (WebServer.ini) to take effect immediately; Except for high-speed, optimized IO processing, speed is not Apache; -> need JAR packaging files to contact: After packaging (JAR package), easy to use, only 2 files: one JAR file and a parameter file; (except generated log file) log record detailed, including client IP addresses, port numbers, machine names, and thread IDs that connect services; thread safety, consumption is not large.
