I have been trying to setup an upload progress bar to my site using both apc and uploadprogress pecl but so far, i can only show the progress bar successfully for smaller files (around 100M😎 but not for files larger than 130MB. Initially, I used ajax to display the progress bar on the same page but it keeps returning blank values for larger files. At first, I thought it might be problem with APC or Uploadprogress Pecl but after i tried displaying the progress bar using javascript pop up windows instead of ajax, i noticed that in firefox, the popup windows displaying the progress bar will sometimes show an error message like the one show in IE about cannot display webpage or cannot connect to server. when i refresh the pop up windows, it can continues to show the progress correctly.
I have been trying for months to figure out this problem and hopefully someone out there can enlighten me. Many thanks in advance...
