Hi guys, I need your help to help me identify a problem. I’m running an  
online marketplace here in Indonesia. Right now I have 1 mod perl server  
using apache and 1 nginx server as proxy. But some of my users complain  
they cannot access my website, [http://www.tokopedia.com](http://www.tokopedia.com). And I found out  
a fact that if they use mikrotik HttpProxy, they cannot access my  
website, but they can access other website.

If they use firefox, they found err message : Content Encoding Error  
If they use google chrome, they found err message :  
ERR\_INVALID\_CHUNKED\_ENCODING

Can you help me with this?

The messages suggest there is something wrong with the proxy in  
question, most likely it fails to handle chunked encoding  
properly. You may try to disable use of chunked transfer encoding  
with

```
chunked_transfer_encoding off;

```

to see if it helps. Note though that it will also make keepalive  
connections impossible if Content-Length isn’t known. You may  
also try to disabling keepalive connections completely with

```
keepalive_timeout 0;

```

See here for details:
