Hi guys,

Just wondering if anyone has done any work on a nginx ESI plugin?

Edge side includes. Used so you can cache part of a page even when some  
small part of the page is not cachable.

Hi Sergey,

> WTF ESI? Could you provide more information.

ESI stands for Edge Side Includes (think of it as SSI for CDNs or  
enterprise  
SSI).

Specification was created mostly by Akamai.

Hello Kingsley,

> Just wondering if anyone has done any work on a nginx ESI plugin?

Actually, I was looking into specification few days ago because I wanted  
to  
make one (only ESI language and basic invalidator, not full spec). But  
for  
now, this is on my TODO list as a one of the “cool projects to make”  
(and  
it’s ranked #3), so don’t expect to see it anytime soon, because neither  
I  
nor any of my clients really need it at the moment.

As far as I know, there isn’t any ESI implementation for nginx.

Yeah, that is my project. Not too active. For a working implementation  
I  
recommend mongrel-esi.

Duh, it seems like I didn’t do my homework. Thanks!

> just out of curiosity what is number #1 and #2 🙂

#1 is ngx\_postgres, which should be out in a couple of days,  
#2 is front-end / router for distributed file system, which name, for  
various reasons, I won’t mention at the moment (but it isn’t MogileFS  
nor  
GridFS).

Have you got a working example by any chance?
