JS cache issue

[tom007]

Hi ,

I am developing a section where we are going to host 1000's of videos. Now most of the site is going to be coded in ajax. So there are going to be several js files

My question is , is it good t cache those js files so save time and make your page load faster? Those files are going to be change once a month, so can be put something in the headers to download it again if it was modified since last access time

Yes, there is a header for that. If I remember correctly it's

<?PHP
header("Pragma: no-cache");
header("Cache-Control: private, must-revalidate");
?>

This is the header currently sent by my application

post-check=0, must-revalidate, no-store, no-cache, pre-check=0

So basically, it is revalidating each time....

I have explained more about this issue in this thread
