a lot of browsers don't support gzip encoding, even IE 5.x will choke if you use mod_gzip. Propel's solution is proprietary and it also does things like ad blocking via regexp (although that's nothing that dansguardian can't do). it's also helped by the huge local cache that the Propel client uses. actually the Propel Web Acceleration Server or PWAS/PAS uses a variety of open-source components such as squid and Python (the server-side proxy is actually a Python application). all in all, nothing magical, but you have to see it to believe it. i mean, for a long time i didn't care about these so-called dialup accelerators, but for a home dialup it literally means the difference between "unacceptable" and "acceptable" browsing experience. you can get to try Mozcom Netrocket (the rebranded Propel we're using) simply by purchasing a Nitro prepaid internet card, which is bundled with a 7-day Netrocket trial. then download the client from www.mozcom.com/netrocket/ -- Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
