As I understand it, whether an item is cached by the web browser is determined by:
- What the response headers tell the browser to do (e.g.,
Cache-Control
andExpires
). - The presence of a validator (e.g., ETag or Last-Modified header).
How does this differ for files served from a network file-share? Across different browsers? Consider this JavaScript include:
<script type="text/javascript" src="\\SOMECOMPUTER\folder\file.js"></script>
Will browsers obey a meta
tag such as this one when network files are involved?
<META HTTP-EQUIV="EXPIRES" CONTENT="Mon, 31 Dec 2011 11:12:01 GMT">
I'm finding very little documentation on this topic.

might actually bez:\SomeShare
which is a network drive mapped to\\SomeComputer\files
