You might be glad to hear that parsing binary data, is **NOT** one of them. If you don’t have to worry about microseconds and the biggest concern is development time, PHP might be in fact a very good tool for the job.

Reading PHP session from Varnish Cache

In my previous post I showed how to integrate Varnish Cache with a PHP application. The example can solve various simple problems but it might not be enough for a complex software. A good example is a multilingual application. One URL can have multiple caches. You might also need to know more about a user (is he logged in? has he received a notification? etc) to make some additional caching decisions.
