Clients can still abort the request or close the connection in many ways - the 
client application crashing, the device crashing, shutting down or running out 
of battery, losing network connection or switching networks etc.

You should probably just ignore these errors unless you suspect the error is 
happening despite any of the above reasons.

RE: Http request with multiple files is not able to read by django server

2014-04-25 Thread Ilya Kazakevich 
Hello,


There may be some web-proxy between client and server that limits request size 
or time. Server may limit it as well.

* Remove all proxies between client and server
* Try to use different client (browser for example)
* Check your server configuration for request size and timeout.

Http request with multiple files is not able to read by django server

2014-04-25 Thread kousik chowdhury 
I am trying to send multiple files(images and audio) from an android device 
using `MultipartEntityBuilder` (java) with http request. Everytime request 
including files reaches server and is working as expected but 
sometimes(10%) django server is not able to read the content of the request.

After going through all the links related to this problem, I come to know 
that this problem may happen because of the **broken request** That is if 
someone cancelled the request in between.

As my request is an `AsyncTask` to the request should not break.


> I know this question is already asked. As I didn't get a proper solution 
from these posts, I want to reopen the issue. So instead of making this as 
`duplicate` ,please try to give me some light.
