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

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.
