How to expire a .js and .ccs page?

[MrMajik]

I have a need to expire .js and .ccs pages because when I modify an existing page the user needs to refresh the site to see the changes. If I could expire these two types of pages or assign them a date from the past then they would expire the next time a person visits the site.

Any ideas?

Thank you.

Hi mate,

The easiest way to do this is to call the js or css page with a random query string.

If you are using an server-side language then this is simple and can be done automatically, otherwise you would really need to change the query string manually everytime you change the file.

file.css?453435343

Hope this helps

Wullie,

I do not know the meaning of your example. Can you explain it?

Thank you.

Wullie means append a random query string to the end of uopr css link declaration:

<link rel="stylesheet" type="text/css" href="file.css?453435343" />

The css file will completely ignore the query string. The easiest way is to add in a timestamp from the server, so it looks unique each time.

Makes cacheing useless though, so it will drain bandwidth and slow the site down.
