Web dispatcher publication issue
We have a problem with publication through web dispatcher, here's the configuration:
wdisp/system_conflict_resolution = 1
wdisp/system_0 = SID=SD01, MSHOST=sd01.domain.com, MSPORT=8100, SRCVHOST= alias01.domain.com
wdisp/system_1 = SID=SD01, MSHOST=sd02.domain.com, MSPORT=8100, SRCVHOST= alias02.domain.com
icm/server_port_0 = PROT=HTTP,HOST=WEBDISPATCHER,PORT=80
icm/server_port_1 = PROT=HTTP,HOST=localhost,PORT=81$$
When we try to access with Internet explorer from internet the logon mask force us to use logon through popup, and it redirect us to an url with "sap-system-login-basic_auth=X" and return a 404, but if we use mozilla we have a normal logon and it works fine.
If we try to access it from the LAN with the real name of the machine even in Explorer we haven't any problem.
Could you please help us to understand what means the url "sap-system-login-basic_auth=X" and how to remove it from all the browser.
