Protocol “” is unknown



  • I'm using simple browser made with Qt WebKit (Qt version 5.2.1).

    On a page (running local rails server) I have a link that opens Pdf Previewer (pdf.js). In this .js script I try to open local (rails) url with path as parameter. Path can be local file path or some public url.

    example:

    http://localhost/documents/preview_file?path=http%3A%2F%2Fmy-domain.s3.amazonaws.com%2F4533902%2Ftest.pdf%3FAWSAccessKeyId%3DAKIAJWDKNPWPFJYREP6Q%26Expires%3D1480381051%26Signature%3DCqfAmGCm7S5lTpQ7pP0U25BqYpE%253D
    

    In case parameter path is public url rails only redirects to this url.

    But problem is, that in this browser I get an error (in console):

    GET http://localhost/documents/preview_file?path=http%3A%2F%2Fmy-domain.s3.amazonaws.com%2F4533902%2Ftest.pdf%3FAWSAccessKeyId%3DAKIAJWDKNPWPFJYREP6Q%26Expires%3D1480381051%26Signature%3DCqfAmGCm7S5lTpQ7pP0U25BqYpE%253D Protocol "" is unknown
    

    I get this error only in this QtWebKit browser, Chrome and Firefox open this link without problem.

    Any help appreciated
