Abstract
In one or more examples, a network proxy agent runs inside an isolated (e.g. sandboxed or virtualized) execution environment and a non-isolated application (e.g., web browser) instance runs outside of the isolated execution environment. The network proxy agent acts as a proxy in the sense that network traffic to and from the application instance is routed through the network proxy agent, and thus via the isolated execution environment. A content access policy is supplied to the content access policy agent, and the content access policy agent enforces the content access policy inside the isolated execution environment in relation to the network traffic. For example, content from a certain resource may be restricted according to the content access policy, in which case content requested from that resource is contained within the isolated environment, and replacement content is served to the non-isolated application instance instead.
