Pretty useful if you don't have the ability to use IIS compression (or choose not to) - Jeff Julian has released a 'plugin' for .TEXT which enables you to compress the RSS feeds produced by .TEXT 0.95 - which is very useful, most of my traffic for instance comes from the RSS feeds (I get around 200 HTML compared with 1800 RSS views per day).
This uses the HttpCompression module by Ben Lowery, which is in itself a brilliant way to enable compression. Ben also links to a MS hotfix rollup package which fixes an issue with HttpModules and Server.Transfer - am I the only one who's rerally annoyed that you have to contact MS to obtain this - what's wrong with just providing a download link (oh, I'm not - and i even mentioned this before)?
