I'm trying to upload a file (which can be quite large) from the website of one server to the backend of another server using plupload. Lets say:
domain 1 = http://www.websitedomain.com/uploadform domain 2 = http://www.backenddomain.com/uploadhandler
Trying to upload i send the following:
OPTIONS /main/uploadnetwork.php HTTP/1.1 Host: backenddomain.com Connection: keep-alive Access-Control-Request-Method: POST Origin: http://www.websitedomain.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.79 Safari/537.4 Access-Control-Request-Headers: origin, content-type Accept: */* Referer: http://www.websitedomain.com/uploadform Accept-Encoding: gzip,deflate,sdch Accept-Language: nl-NL,nl;q=0.8,en-US;q=0.6,en;q=0.4 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 DNT: 1
But when I try to start the upload the server returns the following:
HTTP/1.1 405 Method Not Allowed Allow: GET, HEAD, OPTIONS, TRACE Content-Type: text/html Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET X-Powered-By-Plesk: PleskWin Date: Mon, 01 Oct 2012 12:41:57 GMT Content-Length: 999
After doing some research I found out that a browser does this to check if the server will accept the intended message. It looks like my server doesn't feel like accepting a simple POST call even tho i use post all the time.
The Google Chrome console gives the following error:
XMLHttpRequest cannot load http://www.backenddomain.com/uploadhandler. Origin http://www.websitedomain.com is not allowed by Access-Control-Allow-Origin.
Does anyone know how to stop the browser from checking or how i can tell my server to just accept the POST?
