Abstract: A method of delivering images by an edge server to a web browser is disclosed. It includes receiving through an interface a request for an image file. It includes detecting by a processor the image file as a non-interlaced image file. It includes converting by the processor the detected non-interlaced image file to a corresponding interlaced image file. It includes sending a first segment of the corresponding interlaced image file in response to the request for the image file and delaying delivery of a second segment of the corresponding interlaced image file until a subsequent request for the second segment of the corresponding interlaced image file is received.

The application can begin to access the initial portions of the file by accessing the modified file. The application can access the remaining portions of the file using the at least one placeholder.

Abstract: A content tag is translated. Dynamic content that includes one or more identification tags identifying one or more cacheable portions of the dynamic content is received. The one or more identification tags within the received dynamic content are translated to generate a conventional version of the received dynamic content. The generated conventional version of the received dynamic content are provided.

Abstract: A method of restricting usage of a Document Object Model (DOM) application programming interfaces (API) is disclosed. A DOM virtualization layer intercepts a usage of a DOM API associated with one or more scripts running on a web browser. The DOM virtualization layer determines whether the usage of the DOM API by the one or more scripts is allowed based on a DOM API access control list, wherein the DOM API access control list excludes usage of the DOM API by at least some scripts. The DOM virtualization layer processes the usage of the DOM API based on the determination.

Abstract: A method of distributing content to an application from a server is disclosed. The method includes detecting in a file to be sent to the application from the server that the application is directed to request one or more resources to be downloaded to the application. A network latency associated with the downloading of the one or more resources is determined. A subset of the one or more resources is selectively packaged based at least in part on the network latency. The selectively packaged subset of the one or more resources is sent to the application.

Abstract: Tracking web content updates is disclosed. An indication that a web content has been updated is received. It is tracked that the web content has been updated. An update to a client that a version of the web content stored in a web browser cache of the client is no longer valid is provided.

Abstract: A request for a resource of web content is received. It is determined whether the request identifies the resource using a transformed identifier that has been generated by transforming an original identifier of the resource. In the event it is determined that the request identifies the resource using the transformed identifier, the transformed identifier is translated back to the original identifier of the resource. The resource is obtained using the original identifier of the resource. The obtained resource is provided as a response to the request for the resource of web content.

Abstract: A method of speeding up the delivery of a dynamic webpage is disclosed. A request for a webpage is received, the webpage including one or more dynamic components. A cached stub is sent in response to the request, wherein the cached stub includes components empirically determined as static components of the webpage, and wherein the cached stub includes a placeholder replacing at least a portion of a first dynamic component of the webpage. A script is injected in the cached stub that intercepts any access to the placeholder.

Abstract: A method of speeding up the delivery of a dynamic webpage is disclosed. A plurality of responses to a plurality of requests for a webpage is received, the webpage including dynamic components. The plurality of responses is compared to identify common and dynamic components across the plurality of requests. A cached stub is dynamically adapted based on the comparison within a learning window, the cached stub including the identified common components and placeholders for portions of the identified dynamic components. The dynamically adapted cached stub is sent in response to at least some of the plurality of requests for the webpage. A frequency of reloading of the webpage is monitored, wherein a reloading of the webpage is triggered by a detection of the dynamically adapted cached stub having one of a plurality of types of error. The learning window is adjusted based on a frequency of reloading of the webpage.

Abstract: A method of speeding up the delivery of a dynamic webpage is disclosed. A request for a webpage is received, the webpage including one or more dynamic components. A cached stub is sent in response to the request, the cached stub including common components of the webpage that were empirically determined to be common components across multiple requests for the webpage. The request for the webpage is forwarded to an origin server. The webpage is received from the origin server. A difference between the cached stub and the webpage received from the origin server is determined. An instruction to correct the difference between the cached stub and the webpage received from the origin server is sent.
