Abstract

A method and system for capturing web content from a web server includes a capturing server establishing an active link between a client device and the capturing server that allows the client device to remotely control an active web browsing session, between the capturing server and the web server, to select web content. The method also includes establishing the active web browsing session between the capturing server and the web server using a web browser executing on the capturing server. The capturing server further receives the web content from the web server, without the web content being routed through the client device, and captures the web content during the active web browsing session as a set of images of the web browser. The set of images is captured to a non-volatile storage device, remote from the client device, for later retrieval on a future date.

Claims

1. A method performed by a non-user operable capturing server for capturing web content from a web server, the method comprising:

the capturing server;

establishing an active link between a user-operable client device and the capturing server that allows the client device to, using a remote control protocol executing on the client device, remotely control an active web browsing session, between the capturing server and the web server, to select web content;

establishing the active web browsing session between the capturing server and the web server using a web browser executing on the capturing server;

receiving from the client device over the active link an indication of a selected webpage, and a selection of expandable portions of the webpage;

responsive to the selection by the client device, expanding the expandable portions of the selected webpage within the web browser executing on the capturing server;

receiving the web content from the web server without the web content being routed through the client device;

capturing the web content during the active web browsing session as a set of images of the web browser, wherein the set of images is captured to a non-volatile storage device, remote from the client device, for later retrieval on a future date, wherein capturing the web content as the set of images of the web browser comprises capturing the selected webpage after it has been expanded within the web browser executing on the capturing server; and

providing image data representing the web content to the client device.

2. The method of claim 1 further comprising the capturing server receiving, over the active link from the client device, an indication of a selection of the web browser.

3. The method of claim 1 further comprising the capturing server blocking the client device from uploading content to the web browser during the active web browsing session.

4. The method of claim 1 further comprising the capturing server blocking at least one interaction of the client device with the web browser at a moment of capturing the set of images of the web browser.

5. The method of claim 1 further comprising the capturing server:

sending to the client device over the active link a list of expandable portions of the selected webpage; and

wherein receiving the selection of expandable portions of the webpage comprises receiving from the client device over the active link an indication of a set of expandable portions selected from the list;

wherein expanding the_expandable portions of the selected webpage within the web browser executing on the capturing server comprises only expanding expandable portions included in the set of expandable portions selected from the list.

6. The method of claim 1, wherein the captured set of images comprises multiple screenshots of a webpage, wherein each of the multiple screenshots captures a different portion of the webpage.

7. The method of claim 6, wherein sequential screenshots of the multiple screenshots overlap by an amount of overlap.

8. The method of claim 7 further comprising the capturing server receiving, over the active link from the client device, an indication of a measure of overlap, wherein the measure of overlap specifies the amount of overlap.

9. The method of claim 1 further comprising the capturing server:

applying a comparative algorithm to a first portion and a second portion of a webpage selected for capturing as consecutive screenshots;

comparing a second output of the comparative algorithm for the second portion to a first output of the comparative algorithm for the first portion;

capturing the second portion in a second screenshot after capturing the first portion in a first screenshot in response to the second output not matching the first output.

10. The method of claim 9, wherein the comparative algorithm is a hash function, and wherein comparing the second output to the first output comprises comparing a second hash value generated for the second portion of the selected website to a first hash value generated for the first portion of the selected website.

11. The method of claim 1, wherein the web content selected by the client device is a webpage, and wherein the captured set of images comprises multiple screenshots of the webpage, the method further comprising the capturing server:

loading the webpage into the web browser executing on the capturing server; and

scanning the webpage to initiate loading of objects embedded in the webpage prior to capturing the webpage.

12. The method of claim 1 further comprising the capturing server:

receiving from the client device schedule information;

receiving, in accordance with the schedule information, additional web content from the web server after the active link is taken down; and

capturing the additional web content as an additional set of images.

13. The method of claim 1, wherein the web content selected by the client device is a website identifiable by a domain name, and wherein capturing the web content comprises capturing multiple webpages of the website having the domain name.

14. The method of claim 1, wherein the client device selecting web content comprises the client device communicating a request directing the web server to retrieve the web content based on parameters included in the request.

15. The method of claim 1, wherein:

capturing the web content includes capturing the client device interacting with the web content; and

capturing the web content as the set of images comprises capturing the web content as a video.

16. The method of claim 1, wherein the web content is dynamic web content, and wherein capturing the web content as the set of images comprises capturing the dynamic web content as a video.

17. The method of claim 1, wherein the web content includes audio content, and wherein capturing the web content includes capturing the audio content.

18. The method of claim 1 further comprising the capturing server:

establishing a network connection between a network storage device and the capturing server, wherein the network storage device is remotely located from both the capturing server and the client device; and

sending the captured web content over the network connection for storing on the network storage device.

19. A non-user-operable capturing server configured to capture web content from a web server, the capturing server comprising:

a first wired or wireless interface configured to establish an active link with a user-operable client device;

a second wired or wireless interface configured to establish an active web browsing session with a web server;

a processor operatively coupled to the first wired or wireless interface and the second wired or wireless interface, wherein the processor is configured to;

establish the active link with the client device that allows the client device to, using a remote control protocol executing on the client device, remotely control the active web browsing session, between the capturing server and the web server, to select web content;

establish the active web browsing session with the web server using a web browser executing on the capturing server;

receive the web content from the web server without the web content being routed through the client device;

capture the web content during the active web browsing session as a set of images of the web browser, wherein the set of images is captured to a non-volatile storage device, remote from the client device, for later retrieval on a future date;

provide image data representing the web content to the client device;

receive from the client device over the active link an indication of a selected webpage, and a selection of expandable portions of the webpage; and

responsive to the selection by the client device, expand the expandable portions of the selected webpage within the web browser executing on the capturing server;

wherein capturing the web content as the set of images of the web browser comprises capturing the selected webpage after it has been expanded within the web browser executing on the capturing server.
