I tried to do test virtual host but the following error
Could not find host or port information
Message no. SHTTP082
The system could not find any host or port information.
Possible causes are:
The Internet Communication Manager is not active. Use transaction SMICM to check whether the Internet Comunication Manager is active.
The Customizing settings for the host and port assignment are incorrect. Use transactions SMICM and RZ11 to check whether the system settings are correct.
