Standard RSLs can only be used by applications that are in the same domain as the RSL. You can benefit from using standard RSLs if you meet all of the following conditions:

• You host multiple applications in the same domain.
• You have custom component libraries.
• More than one application uses those custom component libraries.

Not all applications can benefit from standard RSLs. Applications that are in different domains or that do not use component libraries will not benefit from standard RSLs.

Standard RSLs can benefit from digests. While they do not require digests, you can use them to ensure that your application loads the latest RSL. For more information, see About RSL digests.

The following is a list of typical applications that can benefit from standard RSLs:

• Large applications that load multiple smaller applications that use a common component library. The top-level application and all the subordinate applications can share components that are stored in a common RSL.
• A family of applications on a server built with a common component library. When the user accesses the first application, they download an application SWF file and the RSL. When they access the second application, they download only the application SWF file (the client has already downloaded the RSL, and the components in the RSL are used by the two applications).
• A single monolithic application that changes frequently, but has a large set of components that rarely change. In this case, the components are downloaded once, while the application itself might be downloaded many times. This might be the case with charting components, where you might have an application that uses you change frequently, but the charting components themselves remain fairly static.
