An integrator, a plurality of adapters corresponding to a plurality of applications, and a proxy are employed to cooperatively provision the applications as a composite application. In one embodiment, the integrator selectively invokes the appropriate adaptors, which in turn, invoke the proxy. Provision is switched from one application to another by the adaptor of a former application invoking the integrator, which in turn, invokes another application, via its adaptor. Each of the integrator and adaptors may through the proxy, modify a provisioned portion of one the applications. Selected ones of the integrator and adaptors may also have operations performed while the proxy is in a pre-proxy and/or a post-proxy state, thereby facilitating the cooperative provisioning of the applications. Further, modifications to facilitate subsequent requests to be redirected back to the integrator are distributed, and performed on the composite application consuming clients.
