Abstract

Speeding up webpage loading by utilizing one or a combination of the following techniques: heuristic pre-loading; increasing the number of connections to a server; resource caching; and, distributed DNS caching. A software module is inserted between the browser and the server, so as to perform the heuristic preloading, to increase the number of connections, to perform wireless caching of resources and DNS query responses. The software module may be placed in various places in the technology stack, for example, inside a home router or in a separate box connected to one'"'"'s router. The module can insert itself by using proxy discovery protocols, or intercepting the traffic going to the router by issuing ARP replies that look as if it is the router. Alternatively, it could overwrite DHCP.

Claims

1. A computerized method for speeding up the downloading and rendering of web pages from a server, comprising:

during download and parsing of an HTML document by a browser, performing a secondary process comprising scanning the HTML document for mention of a resource and, upon encountering mention of a resource, fetching the resource from the server prior to the browser requesting the resource.

2. The method of claim 1, wherein the scanning and fetching is performed in parallel with but independently of the browser'"'"'s processing of the HTML document.

3. The method of claim 1, wherein scanning is performed by intercepting the HTML document transmission from the server to the browser.

4. The method of claim 3, further comprising intercepting all requests sent from the browser to the server and determining whether the request can be fulfilled using resources available from other devices and, if so, fetching found resources from the other device and providing the found resources to the browser without sending the request to the server.

5. The method of claim 1, wherein fetching is performed by initiating a secondary connection to the server.

6. The method of claim 1, wherein scanning comprises searching for pattern matching.

7. The method of claim 1, wherein resources are identified by searching for tag types, file types, or specific text characters.

8. The method of claim 1, further comprising intercepting a request for a resource issued by the browser and determining whether the resource has been already downloaded and if so providing the resource to the browser;

otherwise, relaying the request to the server.

9. The method of claim 3, further comprising intercepting a request for a resource issued by the browser and determining whether the resource has been already downloaded and if so providing the resource to the browser;

otherwise, relaying the request to the server.

10. The method of claim 1, further comprising, for each resource, establishing a separate network connection to the server.

11. The method of claim 1, further comprising performing a process of tree shaker to identify all unused resources that are not utilized to render the web page and eliminating downloading of the unused resources.

12. A method for improving efficiencies of web browsers, comprising:

inserting a proxy module between the browser and a website hosting server;

preprogramming the proxy to;

detect a request for a webpage issued by the browser;

intercept the webpage when received from the website hosting server while allowing the webpage to proceed to the browser for parsing;

inspecting the webpage for listed resources;

sending a request to the website hosting server for each resource listed in the webpage;

upon detecting a transmission for a requested resource issued by the browser to the website hosting server, determining whether the requested resource has been already downloaded and, if so, providing the resource to the browser and preventing the transmission from reaching the website hosting server.

13. The method of claim 12, further comprising storing a hash value for each resource downloaded.

14. The method of claim 13, further comprising:

upon intercepting a transmission for a requested resource, determining whether hash value of the requested resource matches a stored hash value and, if so, fetching a cached resource matching the hash value and providing the cached resource to the browser.

15. The method of claim 12, wherein the resource is at least one of Javascript code and cascading style sheets.

16. The method of claim 12, wherein whenever a webpage resource is requested from the website hosting server, the resource sent by the website hosting server is cached in a node of a network and when another request is made for the same resource, the resource is provided from the node and the request is not sent to the website hosting server.

17. The method of claim 16, further comprising storing a hash value corresponding to the resource together with identification of stored location.

18. The method of claim 17, further comprising maintaining a hash table of all hash values of resources stored on nodes connected to the network together with addresses corresponding to the notes in which the resources are stored.

19. The method of claim 12, further comprising intercepting DNS queries issued by the browser and determining whether corresponding web address is stored on a node and, if so, fetching the web address and providing it to the browser;

otherwise, relaying the DNS query to a DNS server.

20. The method of claim 19, further comprising storing hash value of each intercepted DNS request in a distributed hash table.

21. The method of claim 20, wherein the distributed hash table is stored on multiple nodes on a network.

22. The method of claim 12, further comprising:

prior to sending a request to the website hosting server for each resource listed in the webpage, determining whether to establish a new connection to the website hosting server based on examination of at least one of;

number of resources listed in the webpage, size of the resource, bandwidth of available physical connections, and network traffic, and, if it was determined to establish a new connection, sending the request over the new connection;

otherwise, sending the request over an existing connection.

23. The method of claim 22, further comprising downloading a plurality of resources in parallel over a plurality of connections.

24. The method of claim 12, further comprising performing a process of tree shaker to identify all unused resources that are not utilized to render the web page and eliminating downloading of the unused resources.

25. A computerized method for speeding up the downloading and rendering of web pages from a server, comprising:

Receiving an HTML document corresponding to the web page from a server;

parsing the HTML document;

constructing a document object model (DOM) corresponding to the web page;

traversing the DOM and enumerating all resources identified during traversal of the DOM;

intercepting a request for a resource from a browser issued to the server and determining whether the resource has been enumerated and, if so, relaying the request to the server, otherwise, voiding the request.

26. The computerized method of claim 25, wherein voiding the request comprises returning an error message to the browser.

27. The method of claim 25, further comprising when an outstanding request for resource is identified, checking whether the outstanding request is for a resource that has been enumerated during traversal of the DOM and, if not, closing a server connection for the outstanding request.
