Michael,

1. renaming or make a link to scep is fine for me. On this cisco router you 
can only set the ip addresse, port number and path as option and the IOS is 
adding   "pkiclient.exe?operation=GetCACert&message=OpenCA HTTP/1.0"

2. on "operation" I got following error messages:
General error 700 Command serverInfo Not Supported  (yet ?!?)

requesting the url by browser:
 http://192.168.0.195/cgi-bin/scep/scep?operation=scepGetCACert&message=OpenCA 
HTTP/1.0

3. on "GetCACert" I got following error messages:
General error 700 Command GetCACert Not Supported  (yet ?!?)
http://192.168.0.195/cgi-bin/scep/scep?cmd=GetCACert&message=OpenCA HTTP/1.0


http://192.168.0.195/cgi-bin/scep/scep?cmd=scepGetCACert&message=OpenCA 
HTTP/1.0 is working fine.

I believe the mapping cmd to operation and scepGetCACert to GetCACert is 
broken.
