System and method for monitoring user actions with respect to a resource presented by a web browser

A system comprising:

• a processor;
• and
• a memory having computer-executable instructions stored thereon that, when executed by a processor, causes the processor to:
• receive a first web page from a server;
• inject program instructions into the first web page to form a modified first web page, the program instructions being configured to cause a client browser to:
• monitor user actions with respect to content of the modified first web page on behalf of the proxy server,
• detect the creation of an element of the modified first web page having a source that is a remote uniform resource locator (URL), and
• mark the URL with a marking based on the detection;
• transmit the modified first web page to the client browser;
• receive from the client browser a first request that includes the URL and the marking;
• extract the marking from the first request to form a second request and transmit the second request to the server;
• receive, from the server, a response that includes a resource identified by the URL;
• determine that the response corresponds to the second request;
• determine that the resource is in a first format that is associated with a file viewer that prevents the client browser from monitoring user actions with respect to the resource on behalf of the proxy server;
• responsive to the determining that the response corresponds to the second request and the determining that the resource is in the first format:
• convert the resource from the first format to a second format that permits the client browser to monitor user actions with respect to the resource on behalf of the proxy server;
• and
• transmit, to the client browser, the resource in the second format.

A computer-readable storage medium having computer-executable instructions stored thereon that, when executed by a processor, causes the processor to:

• receive a first web page from a server;
• inject program instructions into the first web page to form a modified first web page, the program instructions being configured to cause a client browser to:
• monitor user actions with respect to content of the modified first web page on behalf of the proxy server,
• detect the creation of an element of the modified first web page having a source that is a remote uniform resource locator (URL), and
• mark the URL with a marking based on the detection;
• transmit the modified first web page to the client browser;
• receive from the client browser a first request that includes the URL and the marking;
• extract the marking from the first request to form a second request and transmit the second request to the server;
• receive, from the server, a response that includes a resource identified by the URL;
• determine that the response corresponds to the second request;
• determine that the resource is in a first format that is associated with a file viewer that prevents the client browser from monitoring user actions with respect to the resource on behalf of the proxy server;
• responsive to the determining that the response corresponds to the second request and the determining that the resource is in the first format:
• convert the resource from the first format to a second format that permits the client browser to monitor user actions with respect to the resource on behalf of the proxy server;
• and
• transmit, to the client browser, the resource in the second format.
