This is a simplest possible implementation of tail -F for a file on the web : every 5 seconds it checks whether the content provided in an URL has grown in size and, if so, retrieves and prints the difference. Usable e.g. for log files available through an apache.
Usage: java -jar WebTail.jar url proxyhost proxyport The proxy arguments are optional.
Status: This is only a barebone implementation which I did since http://www.jibble.org/webtail/ failed me for some unknown reason. Feel free to extend. :-) GPL licence.
