Issues with Images & PDF downloads
I keep getting reports from users who either don’t see images on some lessons of the Tutorial and FAQs or who can’t download the Manual/Lesson PDF files.
The broken images usually fix themselves if you hit the reload button in your browser. You may have to wait a few minutes though. I’m still looking into what’s causing this. For the time being i have disabled the WordPress QuickCache plugin as i suspect it may have something to do with it.
If you can not download the PDF files and instead you get an error message which is formatted in XML like this:
|
1 2 3 4 |
<?xml version="1.0" encoding="UTF-8" ?> - <Error> <Code>AccessDenied</Code> <Message>Request has expired</Message> |
This is because the links to the PDF files expire some time after you have loaded the webpage. A PDF link normally looks something like this:
|
1 2 3 4 |
http://s3.amazonaws.com/screensteps_live/step_images/learngamedev/manuals/1601 /www.learn-cocos2d.com_-_Tutorial__Professional_Xcode_Setup_for_cocos2d_for_iPhone.pdf? AWSAccessKeyId=19JMR1FABXNXQR79AGG2&Expires=1273502837& Signature=DvufVz1rCaKPXz4GyLn4RNbyH5A%3D |
Amazon’s S3 service will expire such a link after some time. Please do not share direct download links to the manual/lesson PDF files since they will expire, instead link to the lesson itself. If you have problems downloading the PDF, please reload the page and try downloading the PDF again.
I’m sorry about the inconveniences this is causing some of you.
