Prevent cache 1
- Thread starter everytime
- Start date
Hi,
Try:
<META http-EQUIV="Expires" CONTENT="Mon, 04 Dec 1999 21:29:02 GMT">
You might not have much luck though - the whole expires/pragma support is, as I understand it, pretty lousy and inconsistent across browsers. :-(
Cheers and good luck,
Joe

everytime, here is some ways 2 do it:
<META HTTP-EQUIV="expires" CONTENT="-1">
<META http-equiv="Pragma" content="no-cache">
<META http-equiv="Cache-Control" content="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="Mon, 06 Jan 1990 00:00:01 GMT">
but looks like it wont work always-aldays..
here is what microsoft suggests 2 us 2 prevent files from cachin: have 2 head sections in the document:
<html>
<head>
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
<title>!!no cache</title>
</head>
<body bgcolor="#FFFFFF">
</body>
<head><META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE"></head>
</html>
but it doesnt work for me too :-(
well, u might add current time or random number to the url, so, page wont be cachin..
<script>
var tmp=Math.floor(Math.random()*10);
top.location="mypage.html?"+tmp
</script>
here is what i do 2 prevent some of my scripts from cachin:
<script language="javascript">
var time_now=new Date();
var secs=time_now.getSeconds()
document.write("<script language=\"javascript\" src=\"scripptt.js"+"?time="+secs+"\">"+"</"+"script>"
</script>
this wuld prevent those script from cachin, u can do the same with any url;
but
IE won't let you access a url when it's not part of your domain (it's a violation of security). - so, u can do that with ur urls only

The suggested trick using
<script language="javascript">
var time_now=new Date();
var secs=time_now.getSeconds()
document.write("<script language=\"javascript\" src=\"scripptt.js"+"?time="+secs+"\">"+"</"+"script>"
</script>
Does not alwayas work if placed in an asp environment. Also, with Netscape browsers, it may give you a run time error. This is surprising since asp is client-side independent. Any one know a possible explanation?

I use the following with my ASP application.
At the top of every page I have the following.
<%
Response.Expires = 1
Response.CacheControl = "Private"
dim uUrl
uUrl = "uUrl=" & Date & Timer
%>
Then for every url link I have in that document I do something like this.
<a href="somepage.asp?<%=uUrl%>">
Or if you already have some key/value pairs in the url it would look something like this.
<a href="somepage.asp?ID=1&Search=NYMX&<%=uUrl%>">
When you view source, you would see something like this.
<a href="somepage.asp?uUrl=9/22/200161368.09">
OR
<a href="somepage.asp?ID=1&Search=NYMX&uUrl=9/22/200161368.09">
That will force browsers to get an updated page for every link that is formatted like that.
The code ..
<%
Response.Expires = 1
Response.CacheControl = "Private"
%>
Sends additional headers for the page to further help prevent caching.
Good Luck
