we deliver micro-site content for our client. Our content is injected into a wrapper that is supplied by another developer.

To deliver our content we host the wrapper as well as the content. The user can access this at

http://fundcentre.newireland.ie/ (try a search for 'bloxham')

For the other content that is not ours, the other developer hosts a similar (though slightly different) wrapper and delivers the content. the user accesses this here:

http://www.newireland.ie/ (try a search for 'bloxham')

The wrapper contains a search box, which does not work for us but it works for the other developer. I took a look at the network traffic with FireBug but it appears that when I do the search from the wrapper that we're hosting, I'm getting a "407 Proxy Access Denied" error. My guess is their proxy has a problem with the fact that the search is being conducted from a page hosted outside the scope of their proxy.

It was also suggested that there were javascript errors on the page that were preventing the search from executing but I can't see any. Also, I don't think I'd get as far as the proxy error if that was the case.

I don't really understand this stuff too well though, so could somebody with a bit more experience please take a look and maybe shed some light on this for me? Thanks.
