Content Expiry

[TheVillageIdiot27]

Before I start I am not 100% sure that this is a JavaScript problem but it is my best guess.

I have an intranet web page (ASP), which creates an XML file on the server by interrogating a database and saving it with a name based on the users logon name.

This page then runs a JavaScript which loads this file into Microsoft’s XMLDOM in addition with various XSLT style sheets and everything is done client side from there without any problem.

				// Load XML
				var objxml = new ActiveXObject("Microsoft.XMLDOM")
				objxml.async = false
				<% response.write("objxml.load(""helpdesk/domobjects/helpdesk_" & strUser & ".xml"")") %>

				// Load Main XSL
				var objxsl = new ActiveXObject("Microsoft.XMLDOM")
				objxsl.async = false
				objxsl.load("helpdesk/domobjects/stylesheet.xsl")

				// Load Events XSL
				var objxslevents = new ActiveXObject("Microsoft.XMLDOM")
				objxslevents.async = false
				objxslevents.load("helpdesk/domobjects/stylesheet_events.xsl")

				// Transform
				document.write(objxml.transformNode(objxsl))

Except...

There are about two things I need the user to do which involve the user running ASP scripts which make changes to the database and other things, at which point the entire page needs a reload.

As the page reloads the ASP script recreates the XML file fine, and any change to the basic page is reflected. However I seem to have to bang the refresh button for about 30 seconds to get the XML object to refresh.

I have checked that all the content expiry headers are set to zero.

Thanks in advance.

This sounds like a browser issue. Make sure your browser is set to get a new page from the server "On every visit to the page." Obviously this is not currently happening. Probably it is set to browser default, which is a BAD idea.

If your not sure how to do this, reply & Ill explain.

At the moment the only thing I have is:

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

in the header section of the page, I have always assumed this would be enough to avoid this kind of problem, but I assume this doesn't apply to supporting pages?

Any help you can give I would gratfully appreciate.

Try using a refresh statement, either in your javascript or asp, depending on the structure of your program:

Thanks for these,

Afraid no luck though, have ended up fudging it so that each time the script loads the page it does so appending a session number onto the end of the file name and deleting previous entries. Seems really rubbish, but at least it works, but I would still love to know if there was a better way of doing it.

I wish I could see this myself, becuase I feel certain that there is a solution to your problem.

Can you send me something, a link or something? If I can't figure it out, I'm sure my boss can. He's been doing web dev since way back when the Web was brand new.
