ADMIN MANAGEMENT

You can create a separated port to connect in the web dispatcher admin
You should create a net port to webdispatcher listen:
icm/server_port_1 = PROT=HTTP,PORT=8999

and redirect the admin to this port:
icm/HTTP/admin_0 = PREFIX=/sap/admin,DOCROOT=./admin,PORT=8999

KNOW ERRORS/ISSUES

**************************************
*** ERROR => PlugInHandleNetData: server: premature EOS (0/620) in request [http_plg_mt. 1801]
**************************************
-----------------------------------------------------------------------------
The PlugInHandleNetData is a function wich analyses the input stream
from the network. This error you get means that some error occured
during receiving the data stream from the server above.
There is generally nothing to worry about, this can be caused by a
temporary network error or some synchronization fault.
-----------------------------------------------------------------------------
This message "PlugInHandleNetData" appears in the icm trace when you are
executing stateful applications and the user session (in SM04) is
already deleted. This session is deleted after the timeout in
rdisp/plugin_auto_logout. After this time the user session in SM04 will
be deleted. This parameter is only used for stateful sessions.
