Abstract

Systems and methods for managing open tabs of an application are provided. In some aspects, a page is presented in a first tab from among multiple tabs open in an application at a computing device. That a content of the page presented in the first tab is different from a default content of the page stored at a web server is determined. Contents of the multiple tabs are retained in a random access memory (RAM). A request is received to reduce an amount of the RAM used by the application. The content of the page presented in the first tab is stored. In response to the request to reduce the amount of the RAM used by the application, a content presented in a second tab from among the plurality of tabs is removed from the RAM.

receiving a request to reduce an amount of the RAM used by the application;

storing the content of the page presented in the first tab; and

removing from the RAM, in response to the request to reduce the amount of the RAM used by the application, a content presented in a second tab from among the plurality of tabs, the second tab being different from the first tab.

2. The method of claim 1, wherein storing the content of the page presented in the first tab comprises:

foregoing removing from the RAM, in response to the request to reduce the amount of the RAM used by the application, the content of the page presented in the first tab.

3. The method of claim 1, wherein storing the content of the page presented in the first tab comprises:

storing, at a disk, in response to the request to reduce the amount of the RAM used by the application, the content of the page presented in the first tab; and

removing from the RAM, in response to the request to reduce the amount of the RAM used by the application, the content of the page presented in the first tab.

4. The method of claim 3, further comprising:

receiving, after removing the content of the page presented in the first tab from the RAM, a request to present the first tab; and

presenting, in response to the request to present the first tab, the content of the page presented in the first tab stored at the disk.

5. The method of claim 1, wherein determining that the content of the page presented in the first tab is different from the content of the page stored at the web server comprises:

determining that a user at the computing device has entered text into an input box of the page, wherein the default content of the page stored at the web server lacks the text entered by the user.

6. The method of claim 1, wherein determining that the content of the page presented in the first tab is different from the default content of the page stored at the web server comprises:

determining that a user at the computing device has selected a user interface component causing a change to the content of the page, wherein the default content of the page stored at the web server lacks the caused change to the content.

7. The method of claim 1, wherein determining that the content of the page presented in the first tab is different from the default content of the page stored at the web server comprises:

determining, based on a caching header of the content of the page presented in the first tab and a caching header of the default content of the page stored at the web server, that the default content of the page stored at the web server has been updated since the page was loaded in the first tab.

8. The method of claim 1, wherein receiving the request to reduce the amount of the RAM used by the application comprises:

receiving, at the application, a memory warning.

9. The method of claim 1, wherein the content of the page presented in the first tab is stored at a content server and in association with a user account, and wherein the content of the page presented in the first tab is accessible via a second computing device having access to the user account, the second computing device being different from the computing device.

10. The method of claim 1, wherein a content of a second page presented in the second tab is identical to a default content of the second page stored at a second web server.

11. A non-transitory computer-readable medium comprising instructions which, when executed by a computer, cause the computer to implement a method, the method comprising:

presenting a page in a first tab from among a plurality of tabs open in an application at the computer;

determining that a content of the page presented in the first tab is different from a default content of the page stored at a web server;

retaining contents of the plurality of tabs in a random access memory (RAM);

receiving a request to reduce an amount of the RAM used by the application;

storing the content of the page presented in the first tab;

removing from the RAM, in response to the request to reduce the amount of the RAM used by the application, a content of a second page presented in a second tab from among the plurality of tabs, the second tab being different from the first tab, wherein the content of the second page presented in the second tab is identical to a default content of the second page stored at a second web server.

12. The non-transitory computer-readable medium of claim 11, wherein storing the content of the page presented in the first tab comprises:

foregoing removing from the RAM, in response to the request to reduce the amount of the RAM used by the application, the content of the page presented in the first tab.

13. The non-transitory computer-readable medium of claim 11, wherein storing the content of the page presented in the first tab comprises:

storing, at a disk, in response to the request to reduce the amount of the RAM used by the application, the content of the page presented in the first tab; and

removing from the RAM, in response to the request to reduce the amount of the RAM used by the application, the content of the page presented in the first tab.

14. The non-transitory computer-readable medium of claim 11, wherein determining that the content of the page presented in the first tab is different from the default content of the page stored at the web server comprises:

determining that a user at the computer has entered text into an input box of the page, wherein the default content of the page stored at the web server lacks the text entered by the user.

15. The non-transitory computer-readable medium of claim 11, wherein determining that the content of the page presented in the first tab is different from the default content of the page stored at the web server comprises:

determining that a user at the computer has selected a user interface component causing a change to the content of the page, wherein the default content of the page stored at the web server lacks the caused change to the content.

16. The non-transitory computer-readable medium of claim 11, wherein determining that the content of the page presented in the first tab is different from the default content of the page stored at the web server comprises:

determining, based on a caching header of the content of the page presented in the first tab and a caching header of the default content of the page stored at the web server, that the default content of the page stored at the web server has been updated since the page was loaded in the first tab.

17. The non-transitory computer-readable medium of claim 11, wherein receiving the request to reduce the amount of the RAM used by the application comprises:
