The customer has a pdf newsletter that weighs 1.63 MB, so it’s not huge.
We send an email with a link to pdf. Or users find the link on the main page of the site. It does not matter.
The problem is that when a user requests a PDF file, the browser sometimes goes into deep freeze. Those. you need to use task manager to kill the browser instance.
You can check the pdf here:
Newsletter
What is stopping is that he does not always fail. The following is a summary of where I was and what I tried.
browsers
The most likely pdf rejection browser is Google Chrome. However, IE also freezes sometimes.
ERROR
Google Chrome sometimes returns the following error (after a long wait):
"A page processing error has occurred. A file I / O error has occurred. The file has a connection timeout.
IE just freezes without a whimper.
ACROBAT VERSION
The file was originally created in Adobe InDesign CS3, a design studio. We just get the pdf. I tried to save the file using Acrobat 7 if there was some compatibility issue. This seemed to fix the problem on one machine, but not on the other ...
GOOGLE RESULTS
Googling shows that there are some issues with Chrome and PDF. I have not found a solution yet. This still does not explain why IE sometimes does not work.
OTHER MEASURES
I clear the cache for each browser between tests. So it could just be a garbled load.
OPENING A FILE WITH ACROBAT PRO
There is no problem opening the file this way.
