Caches

[Graeme]

Hello All,

 

I've been reading up on caches and I once had some code in a site that gave a fresh page every time it loaded but I can't remember how I did it! Any advice will be most appreciated,

 

Thank you,

 

Best wishes

1-

<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">

This directive indicates cached information should not be used and instead requests should be forwarded to the origin server.

 

2-

<meta http-equiv="expires" content="0">

Setting the content to "0" tells the browsers to always load the page from the web server. But you can also tell the browsers how long to leave a page in cache. Instead of "0" you write the date, including time, that you would like the page to be reloaded from the server. Note, the time should be in Greenwich Mean Time (GMT) and written in the format Day, dd Mon yyyy hh:mm:ss. Like this:

 

<meta http-equiv="expires" content="Thu, 19 Oct 2000 00:00:00 GMT">

 

I got these two from a Google search I have not tried them.
