Caching with Connect/Express

[Kevin Ingwersen (Ingwie Phoenix)]

Hey everyone!

My current project is based on using Express - or connect, still trying out which is better… - and serves a good amount of static files that are likely to not change in a long time during production.

But the current cache-hell that I have is pretty … ugly. I mean, just look at this:

http://git.ingwie.me/ingwie/bird3/blob/master/lib/request_handler.js#L59

Isn’t there a MUCH easier solution than the way I chose? I want to be able to cache all the served images, css, js and oj scripts in the browser…but how can I do it „right“? This just looks like a big mess to me really...

A common option to put a caching HTTP reverse proxy in front of node and let that handle all of the caching logic. Varnish Cache and NGINX Content Caching are popular options.

I am using Socket.IO over the same HTTP instance as my Express app. Does a reverse proxy like Varnish or the NGINX method support that?

[Daniel Rinehart]

Yes to both:

Varnish looks very, very awesome. I already have Nginx installed, but the caching options for Nginx seem dizzy to me or I have read wrong pages. Varnish seems very solid and has great reviews about its capabilities. Good thing my server has 5 IPs…and only 2 are actively used. :)
