Some of my users complain that they need to reload forum pages to see their posts they have just posted (this usually happens in internet clubs or their workplace). Means pages are getting cached by their browser (Opera has this feature by default) or proxy-server.
I have added the following lines to my header (below <head> and above <title>):
<!-- no cache headers -->
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="-1" />
<meta http-equiv="Cache-Control" content="no-cache" />
<!-- end no cache headers -->
This helped with Opera, but I don't know if this gonna help with proxy server cacheing.
What can you suggest? |
