Narrowing Down A Strange Problem

Narrowing Down A Strange Problem

I've seen similar behavior over telnet to port 80.  A small sample of
results is below:

GET /index.html
 Hangs until cancelled.  Note, index.html is greater than 1250 bytes.
GET /what/
 No problems.  Directory listing is fewer than 1250 bytes.
Get /what/pictures/
 No problems.  Directory listing is fewer than 1250 bytes.
Get /what/media/
 Hangs until cancelled.  Directory listing is greater than 1250 bytes.

And so on.  You'll also notice that the response to the invalid command
has fewer than 1250 bytes.
