[Mapserver-users] arcims emulation and arcexplorer

[Ed McNierney]

Mark -

No problem.  The ArcMap client seems much cleaner and more well-behaved than the ArcExplorer client - Chris' decoding of what "CustomStream" meant sure eluded me for a while!

Ed,

OK - I see. I thought you were doing ethernet packet-sniffing (that's
different!). 
This HTTPLook is very interesting.
Thanks for the info!

Mark

Well, packet-sniffing by any other name is just as useful <g>.  I just
downloaded HTTPLook and managed to get a complete log of the HTTP
conversation about 5 minutes after I started without writing any code...

Part of the problem is that the complete interface (for which I have no
documentation) is not very "clean".  For example, not all responses are XML
(cmd=GetVersion, for example).

And, as I've just learned from Chris and Sean (and confirmed), the
ArcExplorer client uses the "CustomStream" parameter to select an ArcXML
output format wrapped in a few bytes of binary data, which is not at all
obvious in the data stream if you're expecting it to be text!
