You can use @OP tags as part of the URL to be altered at playback, and these are substituted just as they are for @OP tags in other situations, for example as part of SQL query strings. If a URL contains query parameters, the normal parameter handling code allows you to mark one or more of these query parameters so that their values can be substituted at portal playback.
You cannot, however, use the @OP tag to replace any part of the scheme, host, or port portion of the URL. For example, you cannot use the @OP tag this way:
http://@OP[“host”=“machine.sybase.com”]:4040/path/index.html
You can use the @OP tag in the URL this way:
http://machine.sybase.com:4040/@OP[“path”=“whatever”]/index.html
The @OP tag must contain a suitable default value, as this is used to determine the initial navigation point.
