Some test results from this:

I wrote a short PHP script which dumps as many chars as I tell it to in
the URL, plus the HTTP header of-course.

Tested from home, I cannot access www.more-solutions.co.uk (homepage),
but can access:
    http://www.more-solutions.co.uk/test.php?bytes=10
    http://www.more-solutions.co.uk/test.php?bytes=100
    http://www.more-solutions.co.uk/test.php?bytes=1000
    http://www.more-solutions.co.uk/test.php?bytes=1200
    http://www.more-solutions.co.uk/test.php?bytes=1276
but cannot access:
    http://www.more-solutions.co.uk/test.php?bytes=1277
.. and above.

If I use:
    wget -s http://www.more-solutions.co.uk/test.php?bytes=1276
.. I get a file of 1411 bytes (ie including HTTP headers etc). An MTU of
1458 means this is below the MTU with a bit of a margin, implying that
the actual MTU limit should be lower still?

I am getting so confused!!
