Forcing No Cache

[mike2010]

What's the proper way of forcing all visitors regardless of which browser their using...to have no cache of our home page ?

I'm currently using -

<meta HTTP-EQUIV="Pragma" CONTENT="no-cache">

It only seems to work with Internet Explorer. Not so much with FireFox or Chrome. (I have to CTRL + REFRESH to get the non-cached version)

Also, it's an index.html page. (not php driven)

Any ideas ?

Thanks much

You can add this:

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

There is also this used by some (change dates accordingly)
<META HTTP-EQUIV="EXPIRES" CONTENT="Mon, 22 Jul 2002 11:12:01 GMT">
but I have never used it.

And if you do not want Google to archive it, add
<META NAME="GOOGLEBOT" CONTENT="NOARCHIVE">

If you ever use .php or .asp pages, there are other options with those scripts.

ASP example in the header:

<%
Response.Expires = 0
Response.Expiresabsolute = Now() - 1
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"
Response.CacheControl = "no-cache"
%>

And here is a useful tutorial [mnot.net] on the subject.

Hope this all helps. :)
