From PHPClasses.org today, there's a new article describing the combination of a few technologies - more specifically Ajax, Comet, and PHP - to create responsive applications.
This post describes an approach used to implement highly responsive AJAX applications using the COMET approach. It describes in detail how the AJAX COMET approach can be implemented in PHP.
It also discusses how HTTP compression and chunking affect AJAX response delays, as well aspects that may influence the choice between Apache 1.3.x with mod_gzip versus Apache 2.x with mod_deflate for AJAX COMET applications.
Manuel breaks the tutorial up into sections:
- Multiple response AJAX requests
- COMET: Multiple response AJAX request implementation
- HTTP compression
- Page compression delays
- Avoiding mod_gzip dechunking
- Apache 2.2.x with mod_deflate
