Access Context Auditing: Prevent recording repeated cookie accesses

To reduce the number of records pending update in the access context
audit database, an in memory set of previously seen cookie accesses is
added. This set is consulted before attempting database insertion and
is cleared on navigation.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
