404 errors on my website

I've been investigating 404 errors on my website.
There are assorted 404 errors, including quite a few apparently
mis-linked images.
These occur from a variety of based generated pages (eg something like
"http://mydynamicsite.com/upbin/oform", containing a base href like
'<base href="http://mystaticsite.com/">' in the head). The image
references are things like "media/top.gif", and this gets linked to
http://mydynamicsite.com/upbin/media/top.gif rather than
http://mystaticsite.com/media/top.gif
They're all (apparently) from one accessor/cache server (gtw-13.nhs.uk),
using MSIE 6 (for the page), and BorderManager 3.0 (for the images). I
suspect it's a cache server because it's so busy. The pages work
correctly for all other accessors.

Anyone know of this issue ? Should I worry ? Can I provide a workaround?

Thanks,
Chris

If you're using Apache, how about adding a rewrite rule like:

RewriteRule ^http://mydynamicsite.com/upbin/media/(.*)
http://mystaticsite.com/media/$1 [R=301]

(all one line, of course). Other web servers should have similar
functionality.

Not using Apache, but do have similar functionality.
It doesn't support passing requests to other web servers, though: these
two aren't virtual hosts on the same machine; they're different servers,
different architectures, with different owners in different cities.
Nice idea though.

Thanks,
