Hi,

I've a client in JavaScript and a server in Django,
I'm trying to send a very long html text buffer (more than 20,000 characters) to the server.
I think that the best way is to convert is to a file in the client and send it as a file to the server,
but i didn't find a way to do it.

first I tried using post:
var string = escape(html_code);
var params = "value=" + string + '';
var xhr = new XMLHttpRequest();
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.setRequestHeader("Content-length", params.length);
xhr.setRequestHeader("Connection", "close");
xhr.send(params);

Open in new window

but it worked for me only for up to ~10,000 bytes:

than I saw that there is a way to send it using blob:
var blob = new Blob([string], {type: 'text/html'});
...
xhr.send(blob);

Open in new window

But I didn't find a way to get it to work / get it on the server..

also tried:
var xmlDoc = parser.parseFromString(string, "text/xml");

Open in new window


any idea?
thanks!
