Issue with unknown browser..

[Chizl]

I have a C# developed web service.. Everyone once in a while I see it not
running.. There are no logs saying it was shutting down, no eventlog saying
there was an error or it was being shutdown, just isn't running. This has
happened 3 times in the last week. What I did notice is the header of the
browser that is talking to me has "x-flash-version: 9,0,47,0" in it.. This
isn't normal for any browser headers I've seen. Can anyone identify what
type of client/browser puts this in the header when talking to a web server.
I just want to find the issue so I can fix it..

Oh and BTW.. I noticed the IP is always my IP.. As if something is on my
machine and indexing my web server. I don't have anything of the sort that
I know of and I'm not even on the computer during the time it has this
issue.

Why are web *browsers* connecting to your web *service* in the first
place? And why should an odd request shut down your service?

I'd try capturing everything you can about the request so you can
reproduce it.
