Re: [xmljs-users] Load xml from local site

[David J. <dj...@ya...>]

Hmmm... Good question. Is this a problem you're seeing in development, or somehow related to a
production issue?

I just tried the following and it seemed to work in Konq and Mozilla. I added the following META
tags to the top of the xml/html data file

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">

It didn't seem to affect the data being returned to the IO function and it also seemed to allow
the file to avoid being cached.

Please give that a shot and let me know if it works for you...


Best regards,

David
