A user might be unable to login to NetMaster WebCenter because of error 'No Cookie Support' occurring
persistently trying to invoke the WebCenter login page.
How to resolve error 'No Cookie Support' invoking the NetMaster WebCenter login page?
In r12.2 the default setting for the web interface is secured. But if your port is not secured then you will
get the No Cookie Support error--which is misleading. To resolve it you should follow these steps:
a) U on $NM WEBCENTER Web Interface Controls (on /PARMS)
b) Change the value of Enable Secure URL Prefix to NO
c) PF06 to ACTION
d) PF03 to SAVE
e) Also: Use http instead of https for the WebCenter URL.
