How can I preview websites that I have stored locally as if I were on
a slower internet connection?

Ideally, I would like a browser or a plugin for IE/Netscape that'll
simulate capping my bandwidth at a certain speed.  I mainly want to do
this because macromedia flash has a built-in bandwidth profiler, but
it doesn't work 100% accurately...i.e. doing a LoadMovie is
instantaneous in the preview mode.  As a result, I want to see my
websites through the eyes of a slow, uncached, internet connection.

I have found a program that caps your internet speeds to certain
levels in order to simulate just this thing. I had seen it on a forum
a while back, so I went there looking for it.

the url for the program is and as you
might guess from the url the name of the program is nimbus by shunra.

search strategy: then search for "bandwidth

This program only works on Windows NT, 2000 and Xp with full service
packs. If this doesn't work on your system, or you have any other
questions, please leave a request for clarification and I will find a
similar program that works for you.

Thanks for the help.  This does help me view the rest of the Internet
on slower bandwidths.  However, when I look at pages that are stored
on a webserver running on my computer, i.e., I visit something like
http://localhost/ it comes up lightning fast, as if it is reading it
straight from my hard drive.  Ideally, I would like to slow that down
as well, as if I were on a slower conenction.

that is an interesting problem, since indeed it is reading the file
directly from your hard drive. I have one suggestion and two
possibilities. The first possibility is that if you could tell me the
name of the webserver software you use, I may be able to figure out
how to set it to do rate limiting. The second possibility is that if
you have access to a proxy server you can set your browser to access
all web sites (even local ones) through this proxy. Then the rate
limiting software you have should work as advertised. If this
possibility sounds good, I can provide a list of public proxy servers
that should do the job.

As for the suggestion, I would suggest that if you have access to
another computer on your LAN, then you can use the utility I pointed
out, and even though the webserver is on the same network, you will be
able to simulate much slower speeds.

Do any of these options sound good? If so, and you need more
information, please let me know which options sound most appealing and
I will get you more specific information as soon as possible.

Thanks funywizard.  Yes, those are wonderful suggestions and I think
those would help.  Do you know any good public proxy servers or
whatever (link that has them maybe).  Maybe even software.  Yeah,
you're right, the bandwidth throttling should work over the network,
although I don't have an extra computer on the network.  As for the
server I'm using, it's apache on windows.  I got it from nusphere.  I
don't know if there's an easy way to do rate limiting in apache.  The
proxy solution might work best.

Is there a way that I can add more money to the question?  Like $5. 
Sound good?

I just checked in right before heading to class, so when I get back
I'll make up a list of proxy servers. Also there is a program I use
called multiproxy, but more on that in a bit.

As for additional money, Google Answers provides the option that if

In any case, I'll get back to you on those public proxies in a couple

I looked into lists of public proxy servers, and I've come up with a
few web sites with such lists. In my experience, such lists have about
30% or so of the listed proxies actually working well enough to be
worthwhile, so I have picked a couple out that worked for me.

In order to use a proxy in internet explorer, you would use the menu
and click Tools->Internet Options, then click the connections tab,
then Lan settings, then check the box that says "use a proxy server"
and input the ip address of the server in the first box, and the port
number of the server in the second box. Make sure the check box that
says "bypass proxy to connect to local sites" is disabled.

Also make sure that when you view your webpage, you use your machine's
actual public internet ip address, instead of a local one (,
localhost, 192.168.0.*, or any other non internet accessible ip
addresses). If you need help finding out what your ip address is, I
give you information on that as well.

Often, in a proxy list, you will see the proxy listed as something
like this The first set of four numbers is the
ip address, and the numbers after the colon is the port number.

A program called multiproxy ( ) will
automate the usage of proxy servers for you, and provides a
semi-anonymous browsing environment by routing your internet through a
different proxy server for each url you visit. In addition, the
website maintains a list of public proxy servers, and the program has
the facilities to automatically test a list of proxy servers to check
which are working and which do not. A great help if you plan to
continue using proxy servers.

And on to the actual lists!

The first web site I came accross is one that I have used before ( ) and usually has up to date
lists of proxies one may use. They used to allow sorting by fastest
server etc, but apparently now require registration for that.
Nonetheless any of their lists (
) should provide relevant results.

One more website listing public proxies is here ( ) and seems to provide a good

Most useful is that I have checked for a couple proxies that should
work for you. Ones that worked for me are as follows:

address port 3128
address port 80
address port 80
address port 80

I hope this provides you with the information you need. If anything is
unclear or does not work properly, please let me know.
