Abstract: Described herein is a system for enabling a user to multitask by allowing a user to pause or interrupt an on-going interaction with a skill. The system monitors a state of a skill session, and updates the state to allow the user or system to suspend the session. The user may provide an instruction to pause an active session, causing the system to place the session in a suspended state. The user may then provide an instruction to resume the suspended session, causing the system to place the session in an active state. In other cases, the user input may be a request during an active session that requires invoking another skill. The system may place the current session in a suspended state, and invoke a second skill session to monitor the interaction with a second skill. When the interaction with the second skill is completed, the system may resume the previous session by placing it in an active state.

Abstract: Described herein is a system for allocating resources among multiple skills to enable multitasking. The system tracks use of resources using skill sessions. In one case, the system suspends a skill session to release a resource for allocation to another resource. In another case, the system determines if multiple skill sessions can remain active and use resources to provide output to the user at the same time.

Abstract: Disclosed are various embodiments for generating network pages for customers that include customer-generated page portions. A request for a network page is obtained from a client.

The generated network page is sent to the client in response to the request.

Abstract: Disclosed are various embodiments for securing execution of page generation code. The page generation code may be instrumented with code that facilitates monitoring of one or more resources consumed by the page generation code. Various checks relating, for example, to code size and whether exception-handling code is present may be performed. The page generation code may be executed to generate a network page in response to a request obtained from a client. One or more resource consumption limits may be enforced upon the page generation code.

Abstract: Disclosed are various embodiments relating to generating portions of network pages associated with a network site, where the portions of the network pages are generated by page generation code that uses a subset of aggregated data provided to it. A request for a network page is received from a first party. Data is aggregated from one or more data sources in response to the request. Each data source provides multiple data items using a multipart encoding. Page generation code supplied by the first party is executed to generate at least a portion of the network page in response to receiving a subset of the data which is used by the page generation code. The page generation code is able to access the subset of the data as predefined variables.

Abstract: Disclosed are various embodiments relating to virtual file systems for customers having network sites hosted by a hosting provider. A file system with multiple files of a customer is maintained for a hosting provider. Customer access to a virtualized version of the file system is facilitated. The virtualized version of the file system includes a virtual file that is dynamically generated based at least in part on one of the files in response to an access of the virtual file by the customer. The file system excludes the virtual file. A modification to the virtual file by the customer is obtained. The file in the file system is updated based at least in part on the modification to the virtual file.

Abstract: Disclosed are various embodiments that facilitate error handling in a network resource generation environment. A request for a network resource is obtained from a client. The network resource is associated with a network site hosted on behalf of a first party by a second party. Resource generation code supplied by the first party is executed by a framework in response to the request. A customized error network resource is sent to the client in response to determining that an error has occurred in the framework that executes the resource generation code.

Abstract: Disclosed are various embodiments for hierarchical modeling of network sites. A page model from a hierarchy of page models is provided in at least one computing device. The page model includes a plurality of features. Each one of the features is assigned to a respective network page region. The features include at least one original feature and at least one inheritable feature from a parent page model. A network page is generated in the at least one computing device corresponding to the page model. Each one of the features of the page model is encoded for rendering within the respective network page region.

Abstract: Disclosed are various embodiments for network site customization using proxy server applications. A first request is obtained from an administrator of a network site to configure a proxy server application to obtain one or more network pages associated with a first portion of the network site from a first application executed in one or more computing devices. The proxy server application is configured in accordance with the first request. A second request is obtained from the administrator to reconfigure the proxy server application to obtain the one or more network pages from a second application executed in one or more computing devices. The network site includes one of several network sites hosted at least in part through the second application. The proxy server application is reconfigured in accordance with the second request.
