<div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> At the lab the teacher advocates using the Windows equivalent of the<br>
/etc/hosts file to prevent access to certain sites from classroom<br>
computers. He and I have been having an ongoing chat about this for a<br>
few months. I've been reading up on the way the file is used to redirect<br>
requests to a different address (eg. 127.0.0.1). Is there a difference<br>
in the way Windows parses the file compared to Linux?<br>
<br>
One reason for the above question is I was thinking it might be useful<br>
to redirect requests to advertising sites to 127.0.0.1 to speed up<br>
access on days when things seem to crawl. One article I read on Digg<br>
suggested a lot of the wait time for web pages was due to slow and<br>
misconfigured ad servers. I found one site which has example files which<br>
are updated so often. I tried one and I got almost nothing when surfing<br>
the web. Using the file as a pattern I created a smaller version which<br>
works well with the chromium browser but fails to display text in firefox.<br>
<br>
These are the lines I've added. Yes I know there are duplicates.<br>

Would the "*" in the domain name cause problems? Like I said, I used<br>
the Windows file as an example.<br>
