From the lists, select the access group and SCID (service component ID) you want to work with.
From the list, select the configuration.
To add a request-header definition to a configuration:
From an open configuration, click Edit Configuration.
In the Service-Wide Definition section, click Request Headers.
Media portal lists the request-header definitions for the configuration (if any).
Click New Definition.
Type a name for the definition. (You can leave the auto-generated name or type a name more meaningful to you.)
Fill in the information for the request header:
In the Header Name field, type the name of the request header.
In the Header Value field, type the value to be returned for that header.
To add additional headers, click Add, then repeat steps a and b.
If you need to edit or add other definitions, continue editing the configuration without saving. (Saving the configuration creates a new version.) When you're done editing the configuration, continue with step 7.
Click Save (above the Service-Wide Definition section). You can also click Save As to save the configuration under a new name.
If needed, make any notes to describe the changes you made.
Click Save again.
Media portal saves the configuration with the new definition.
