PDFs failing to load and display RRS feed

  • Question

  • http://www.cyc-net.org/cyc-online/cyconline.html refers.

    Our site is hosted on an IIS server. We have been notified that PDFs (any PDF) from the above URL refuse to load or display. Loading stops at varying instances - usually between 500-900k. We have done some tests and confirm this to be the case on IE10, 11, Chrome and Edge. Firefox works without issue.

    Smaller file size PDFs appear to load without issue. The PDFs from the above URL all tend to be above 10 megs.

    We have also tested by moving some of the PDFs from the above URL to another server (Linux) and they load without issue.

    I'm not sure whether this is an IIS issue or a browser issue, but I'm asking here first.

    Any help appreciated.

    Thanks,
    Martin

  • Hi Stabes,

    We could try the hotfix in the link below to repair.

    https://support.microsoft.com/en-us/kb/979543

    https://support.microsoft.com/en-us/kb/2026272

    Also we could try check the add-on in the browser.

    Internet Explorer:

    1. Go to the Tools menu and click on 'Manage Add-ons'.

    2. Click on the drop down menu "Show" to display "All Add-ons".

    3. Select Adobe PDF Reader and click the Disable button.

     Chrome:

    1. Type (or copy & paste), this into the address bar:    chrome://plugins 

    2. On the next page, to disable plugins, click to disable Chrome PDF Viewer       

    Then we could delete temporary Internet files (Internet Explorer and Chrome)

    Clear the browser cache (sometimes called temporary Internet files) to ensure that you're viewing a fresh version of the page. 

    Be careful when selecting the options. Clear only the browser cache. If you clear all temporary Internet files, you could delete the cookies that contain login information and preferences. Most browsers let you choose the type of content you want to delete.

    Hope it will be helpful to you.

  • Hi,

    try removing the following lines from your google analytics script block.

    var trackOutboundLink = function(url) {
    ga('send', 'event', 'outbound',
    'click', url, {'hitCallback':
    function () {
    document.location = url;
    }

    .... check with google for any updates for their analytics links.

    Why? right-clicking on the current edition image and selecting "Save target as" downloads the 12mb pdf document in seconds, while clicking the image link takes ages.

    Possibly clients using tracking protection lists or not sending the do not track header don't reach the google servers.

  • Thanks.

    Disabling the Adobe PDF Reader Add-On in IE forced a download and that now works.
    Disabling the Chrome PDF Viewer forced a download and that now works.

    Begs the question - unlike me, not everyone will want to go fiddling around with their browser settings. Is there not a way to override these add-ins in a configuration file or something like that?

  • Hi,

    no....not from a web site.... users or network administrators can with their PDF reader settings, Addons manager or through Group Policy. Native PDF document readers were included with Win8.x and higher.... Previous windows versions required a third party product (Adobe and others)... Chromium has its own built in PDF reader....

    It begs the question why your PDF documents are hawking the download.... right-clicking and selecting "Save target as" is fast....

    1. check that you have mapped the correct mime-type for pdf documents in your IIS control panel...

    2. review your publishing methods.... a blog may be appropriate and it will reduce your hosting costs.

    Contact the publisher of your PDF document software... the software that you use to author and publish the PDF documents. They may have restrictions for commercial use or they are not using a recognized standard in their format.
