head scratcher or am I missing something obvious

My first guess is that your hosting company has instituted something like mod_throttle which blocks a connection when more than x simultaneous connections are attempted and that number seems low.

The way downloaders work is that they open 6-20 connections at the same time and fetch things in parallel. This typically puts some strain on the webserver depending on what is being requested. As a method of combating this, many hosting companies use a firewall or apache module that blocks the offending IP for a period of time.

Firefox can be configured to use pipelining which is set to 8 or 12 simultaneous connections at the same time. By default, pipelining is off, but, many of the 'faster web' plugins will enable it.

You might check with your hosting company to see if they have recently added connection throttling like that. It is also possible that his ISP instituted similar caps, but, that would be much less likely.

Hey cd34 ..

that possibly could be it, he has used IE/Firefox/Opera as his browsers, so maybe thats it. Of course a different IP addy sets off our server security .. thanks for the suggestions. I will pass them along.

He is saying he gets this: The error message I get is that I cannot cannot connect to the website. In opera its a blank page and then error, In IE it is page cannot be displayed and in FF it
is the same as opera. It wont connect to your homepage for some reason and yet every other website I visit is ok and I can download from them fine, I am at this
moment downloading from another site fine.

So it is my site that simply doesn't like him !!!
