Hi,

I am using nginx with the long polling module. When 0.7 something was  
new, I compiled nginx with the long polling module and wrote my  
application. It ran under Ubuntu for 18 months or so, without problem.

During this time I have not changed the code that handles messages or  
startup. In fact, there are only two commits to the VCS.

About a month ago, I recompiled 1.0.6 with the long polling module using  
the same script as before. And the application has started to show  
intermittent errors.

Can anyone confirm that they are using the long-polling module with  
1.0.6 without problems?

The symptom appears to be that if the second person to join the chat  
room, does not send a message for 5 minutes and they do not receive one  
in this time either, then they get timed out, and never receive a reply  
to the read issued after the start-up phase.

Regards

Ian

Are you referring to the push module? ([http://pushmodule.slact.net/](http://pushmodule.slact.net/))

or have a look at wandenbergs nginx-push-module, since version 0.3.0  
(master branch) it also support long-polling and polling and its under  
active develpment.

Hello,

We are using the “Substitutions Filter module”  
to replace html content in our pages.

Our configuration is :

location /{  
subs\_filter\_types text/html text/xml;  
subs\_filter ‘[http://bale.hopla.net/bons-plans](http://bale.hopla.net/bons-plans)’  
‘[http://bons-plans.hopla.net](http://bons-plans.hopla.net)’;  
subs\_filter ‘id=“portal-logo” href=“[http://bale.hopla.net](http://bale.hopla.net)”’  
‘id=“portal-logo” href=“[http://www.hopla.net](http://www.hopla.net)”’;  
}

The first substitution is working, but the second not.  
Are we missing something? Is the “space” supported in substitution  
module?

Thank you for your help!

I put the push module into production for a while a few months ago and  
suffered intermittent segfaults. It also has a couple of design  
limitations that were problematic in my case. It doesn’t seem to be  
under active development, so I doubt these issues will be fixed any  
time soon.

But I wonder whether the module isn’t a poor solution architecturally,  
in any case. I eventually dropped it and implemented long-polling in a  
Node.js script. This turned out to be almost trivial – far faster  
than trying to fix the module. Nginx is set up as a reverse proxy to  
this server, so it’s insulated from any bad behaviour. I found the  
stability and ease of maintenance of this design easily worth the  
extra ~50 MB and CPU cycles.

Cheers  
Thomas

It works in my box. Can you show me your debug log?

[http://wiki.nginx.org/Debugging](http://wiki.nginx.org/Debugging)

Do’t use this in the production server. The debug log will be very  
large.

Sorry. I can’t find any log from my substitutions module in your debug  
log.

And I find the possible problem. The response from backend server is  
gzipped. You can compress the response with Nginx’s gzip module.

You should disable the gzipped response from backend server, like this:

proxy\_set\_header Accept-Encoding “”;

Maybe we could check the Content-Encoding response header  
automatically in ngx\_subs and if it’s gzip/deflate, just issue a  
warning to error.log by default? 😉

Maybe the documentation of the module should be completed to notify  
about  
this problem.

Yes, You are right. I’ll add this to the documents. There will be too  
much  
error log if I add this for each request.

You can just log at the debug level maybe? 😉
