Zaxo says it is what you are looking for, ready to go. Seeing you mention slashdot (who get slashdotted all the time ;-) you may be interested to know

Apache::DynaGzip which will gzip your content on the fly (static or dymanic) thus cutting your bandwidth use radically as well as making the end user experience better. Most big sites use some form of gzip compression. In case you don't know browsers can decompress gzip streams so (provided they accept it) you send the content gzipped and they decompress it locally. It is a real win-win.
