A system and method that allows a page (e.g., Internet content) author to associate a set of security settings on any desired element (e.g., tag) of the page. When the page is interpreted, each element is handled based on its associated security settings, allowing a page author to request that any element be considered differently with respect to security than other elements, and/or differently relative to the page that contains it. A negotiator determines the actual settings for elements to ensure that security cannot be compromised by tagging an element such that it has the ability to do more than desired. The negotiator also determines the settings for elements that do not have specifically associated security data, e.g., elements without specified security settings may inherit security settings from higher elements, or the top-level container. The settings may correspond to those of a security zone.

What is claimed is: 1. In a computer system, a method comprising: receiving a page comprising content including one or more elements having active content; and controlling page output corresponding to at least part of the content by: 1) disabling or enabling execution of a first script or loading of a first control corresponding to at least one part of the page based on a first set of security settings; and 2) disabling or enabling execution of a second script or loading of a second control corresponding to at least one other part of the page based on a second set of security settings, the second set of security settings being different from the first set of security settings. 2. The method of claim 1, wherein receiving the page includes accessing data received from a remote source. 3. The method of claim 1, wherein receiving the page includes accessing data received from a cache. 4. The method of claim 1, wherein a first action including one of execution of the first script or the loading of the first control is requested in the content in the at least one part of the page, wherein a second action including one of execution of the second script or the loading of the second control is requested in the content in the at least one other part of the page, and wherein controlling page output comprises, allowing the first action and disallowing the second action. 5. The method of claim 4 wherein the first action corresponds to a command to run the first script, and wherein the second action corresponds to a command to run the second script. 6. The method of claim 4 wherein the first action further corresponds to a command to download a first set of data, and wherein the second action corresponds to a command to download a second set of data. 7. The method of claim 4 wherein allowing the first action comprises, prompting a user for a decision and receiving a response indicating that the first action is allowed. 8. The method of claim 4 wherein disallowing the second action comprises, prompting a user for a decision and receiving a response indicating that the second action is not allowed. 9. The method of claim 1, wherein a first action including one of execution of the first script or loading of the first control is requested in the content in the at least one part of the page, wherein a second action including one of execution of the second script or loading of the second control is requested in the content in the at least one other part of the page, and wherein controlling page output comprises, disallowing the first action and allowing the second action. 10. The method of claim 1 further comprising: retrieving the first set of security settings based on an identifier indicating a source from which the page is obtained, and associating the first set of security settings with the at least one part of the page. 11. The method of claim 10 further comprising, constructing a tree to represent the page, and wherein associating the first set of security settings with the at least one part of the page includes storing data corresponding to the first set of security settings at a node in the tree. 12. The method of claim 1 further comprising: recognizing security data associated with an element of the page, and associating the second set of security settings with the at least one other part of the page based on the security data. 13. The method of claim 12 further comprising, constructing a tree to represent the page, and wherein associating the second set of security settings with the at least one other part of the page includes storing data corresponding to the second set of security settings at a node in the tree that corresponds to the element. 14. The method of claim 13 wherein storing data corresponding to the second set of security settings comprises negotiating the second set of security settings. 15. The method of claim 14 wherein negotiating the second set of security settings comprises inheriting at least one setting in the second set of security settings based on security information associated with a parent node in the tree. 16. The method of claim 14 wherein negotiating the second set of settings comprises receiving at least one setting in the second set of security settings based on security information associated with a child node in the tree. 17. The method of claim 1, wherein controlling page output further comprises, accessing privacy settings. 18. A computer-readable medium having computer-executable-instructions for performing the method of claim 1. 19. In a computer connected to a network, a system comprising: browser software that interprets content received from the network, and a security mechanism that associates a first security zone with a first part of the content and associates a second security zone with a second part of the content, the security mechanism being further operable to associate a first set of security settings with the first part of the content based on the first security zone, and associate a second set of security settings with the second part of the content based on the second security zone, the second set of security settings being different from the first set of security settings, whether execution of a first script or loading of a first control corresponding to the first part of the content is permitted being based on the first set of security settings, and whether execution of a second script or loading of a second control corresponding to the second part of the content is permitted being based on the second set of security settings. 20. The system of claim 19 further comprising, a negotiator that controls the second set of security settings. 21. The system of claim 20 wherein the negotiator controls the second set of security settings relative to the first set of security settings. 22. The system of claim 21 wherein the negotiator controls the second set of security settings relative to the first set of security settings by having at least one setting in the second set be inherited from a corresponding setting in the first set. 23. The system of claim 19 wherein the first set of security settings is based on a network identifier of a source of the content. 24. The system of claim 19 wherein the second part of the content corresponds to an element in the content. 25.
