After you have enabled automatic injection:

• You must specify the server-side business transactions for which automatic JavaScript injection is enabled.
• You can limit which pages to inject by creating custom match and exclude rules for automatic injection. If you do not configure these rules, by default Splunk AppDynamics injects all pages visited by the enabled business transactions.

Use these rules to fine-tune which business transactions to include or exclude from injection based on match criteria. For example, you can exclude all business transactions that have a certain string in their URLs or set a certain cookie. The configurations for include rules and exclude rules are similar. It depends on your situation whether it is more convenient to restrict transactions based on inclusion or exclusion.
