This forum is a community forum meant for users of the plugin to collaborate and help solve issues with implementation, etc. Unfortunately, as the creator of the plugin, I do not have much time to attend to every request here as this is only a side project and I must work a full-time job to provide for my family. This is how I keep the Flash version free and the HTML5 version low cost.
UploadiFive 1.1.1 has been released which includes a small fix for added support on touch devices including iOS 6 devices.
uploadifive cross domain issue
  • mychiimychii
    I have a web server that require me to upload files through cross-domain. I can do this with Uploadify, but Uploadifive complaints on cross-domain issue (Access-Control-Allow-Origin). Is there anyway to solve this?

    Thanks.

    I'm also curious about this issue. Does uploadifive ignore the Access-Control-Allow-Origin headers sent in response by another server?

    For example utilizing node.js as our primary file upload server we submit the following as headers:

    res.writeHead(200, { 'Content-Type' : 'application/json', 'Access-Control-Allow-Origin' : '*' });

    However it seems they are ignored by the uploadifive plugin with the error:

    XMLHttpRequest cannot load *remote url*. Origin *local url* is not allowed by Access-Control-Allow-Origin.

    After tinkering around with headers / and looking at numerous blogs I figured out how to make uploadifive work cross domain.

    https://developer.mozilla.org/en-US/docs/HTTP_access_control

    If you take a look at the link above (jump down to Preflighted requests) you can see the transactions that XHR takes to validate the server as "safe".

    By setting the following headers on my file server responding to the OPTIONS request that XHR makes before the actual POST request to:

    'Access-Control-Allow-Origin' : '*'
    'Access-Control-Allow-Methods' : 'POST OPTIONS'
    'Access-Control-Allow-Headers' : 'X-File-Upload'
    'Access-Control-Max-Age' : 1728000

    and adding a custom header into the XHR request located in uploadifive.js file (around line 489):

    xhr.setRequestHeader("X-File-Upload", "uploadingfiles");

    It successfully validated the request and allowed the files to be uploaded. Hopefully this helps anyone trying to get around crossdomain's utilizing uploadifive.

    IE can use XDomainRequest to solve cross-domain, you should set up a new website in your server to receive you client file. client js should use physical path.
