tproxy + nginx #1

Closed ghost closed 13 years ago

ghost commented 13 years ago

I wanted to use tproxy and nginx to serve static files. When I take my browser to tproxy url, most of the time the browser fail to show the page.

I got this in the console running tproxy with --log-level=debug

To make things more clear at localhost:8000 there is gunicorn, and at 7999 there is nginx. 

here are the versions a used to do the test:```
gevent==0.13.6
greenlet==0.3.1
gunicorn==0.12.1
http-parser==0.3.3
-e git://github.com/benoitc/tproxy.git@0f32b5b0d8a1f004ed060db4729943b37a3306c1#egg=tproxy-dev
wsgiref==0.1.2```

there is an example setup at this repository https://bitbucket.org/abki/ftv/src.

I think it has to do something with nginx, since when I tried gunicorn+file served with tproxy (like in the readme example) it worked well.

I runned this tests on linux 2.6

now with 0.5.4 the exception is gone but the problem keeps happening i.e. the page doesn't show up sometimes.

I did look to nginx logs and stuff and find out (I'm refering to the test I've setup in https://bitbucket.org/abki/ftv/src ) : tproxy doesn't close the connection with nginx as we would expect, but some ms or sec after the initial request was fired. Until then, you can't try to fire up the page again it will result in a forbidden access error from nginx. Having a look at nginx logs I discovered that nginx is requested 3 times: 1) for the images I've put in the gunicron answer 2) for /favicon.ico which is strange since proxy.py filter by path and /favicon.ico is not in the right path 3) for « / » which is more strange actually

So I've hit a wall, I hope I did not do a stupid mistake in my configuration.

You may need to close the connection with the remote if you want to have the route based on the path.
