Problem:
Sometimes I get 200 response, but sometimes 404 (File or directory not found).

If I do request from Russia, Germany or USA, response is 200.
If I do request from China, sometimes response is 404 (Depends on ISP, time and maybe something else).

404 response looks like iis can not find server.js

Example of 200 response (Using express Vpn, connected to USA):

2013-04-29 02:42:58 W3SVC1 LOFT4002 188.138.16.31 GET /zazaza - 80 - 180.150.157.51 HTTP/1.1 Mozilla/5.0+(Windows+NT+6.2;+WOW64)+AppleWebKit/537.31+(KHTML,+like+Gecko)+Chrome/26.0.1410.64+Safari/537.31 connect.sid=s%3ABHin0EtiPcJbD6GCeXE2hb_1.mNHhYwIs%2BvLKcJcXc1igMH4O%2FIkuwQdygd1XjN7ediM - test.amelisa.ru 200 0 0 367 530 514

Example of 404 error (Without vpn, request from China):

2013-04-29 02:32:47 W3SVC1 LOFT4002 188.138.16.31 GET /zazaza - 80 - 112.90.90.18 HTTP/1.1 Mozilla/5.0+(Windows+NT+6.2;+WOW64)+AppleWebKit/537.31+(KHTML,+like+Gecko)+Chrome/26.0.1410.64+Safari/537.31 connect.sid=s%3AdL_RALh0qLd0eLoCxZUk6Po-.N9h97BMFy9%2Fm9tl8lrQd%2FIHQjwpwzEXfWC7f4%2FrHxpY - test.amelisa.ru 404 0 0 1390 532 436

iisnode have no logs neither traces for 404 requests, so I think it`s not even starts for them.

The same issue with all iisnode/node.js sites on this server.
But Asp Net Mvc web site on this server return 200 any case, so it may be not Chinese Golden Shield issue.

I can provide any information.
Any help will be appreciated.

try to create a route to your solution to test like:

//my route to test "GET", make sure if your route is "POST"
app.get('/test', function(req, res){
     res.json(true);
});

Now use the url to test: http://test.amelisa.ru/test

This error happen when there is not route to that path. I was with the same problem and it resolved.

I hope it helps. If not, please, share your code in './lib/server' to help more.
