How To Save Traffic With mod_deflate On Lighttpd 1.4 (Debian Etch)

Post date: August 15, 2007, 22:08 Category: Installing Views: 2776 Comments
Tutorial quote: In this tutorial I will describe how to install and configure mod_deflate on a lighttpd 1.4 web server on Debian Etch. mod_deflate is included by default in lighttpd 1.5, but not in 1.4 where mod_compress is used instead. The advantage of mod_deflate over mod_compress is that it can compress static and dynamic files (such as PHP files), whereas mod_compress can compress static files only. The lighttpd version coming with Debian Etch is 1.4.13, so we have to patch it to support mod_deflate. mod_deflate allows lighttpd to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_deflate, you can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier.

Get More Out of Your Pipe with Apache and mod_gzip

Post date: April 14, 2005, 13:04 Category: Network Views: 2410 Comments
Tutorial quote: Some Web sites seem like they are designed to annoy and alienate visitors. Teeny tiny fixed fonts, weirdo fixed page widths, ad servers on Mars, and the content won't load until the ads do, and all kinds of dynamic jiggery-pokery that does everything but quickly deliver a nice, readable page.

Webmasters who are serious about running high-performance Web servers, and who want pleased and delighted visitors, have a great tool in Apache 1.3's mod_gzip. mod_gzip compresses pages on the fly, reducing their size considerably. Depending on the types of files served, you'll see size reductions ranging from 20%- 80%, and a nice increase in server efficiency. Nothing is needed on the client side, except sane modern Web browsers like Mozilla, Firefox, Opera, Galeon, and Konqueror. Mozilla, Firefox, and Opera are nice cross-platform browsers with all kinds of neat features, so don't be afraid to standardize on one of them.
