| − | Google Chrome is a [[Web Browser|web browser]] developed by Google Inc.
| + | [[User:Joachim Metz|Joachim]] 03:36, 28 July 2012 (PDT) According to project site the last release is 07 Oct 2008, anyone knows if this is still actively maintained? For now I'm marking this as deprecated |

| − | == Configuration ==

| − | === DNS Prefetching ===
| + | |
| − | | + | |
| − | DNS is prefetched for related sites, e.g. links on the page.
| + | |
| − | This behavior is controlled by the setting "Predict network actions to improve page load performance"
| + | |
| − | Which is enabled by default.
| + | |
| − | | + | |
| − | If enabled the Preferences file contains:
| + | |
| − | <pre>
| + | |
| − | "dns_prefetching": {
| + | |
| − | "enabled": true,
| + | |
| − | </pre>
| + | |
| − | | + | |
| − | If disabled the Preferences file contains:
| + | |
| − | <pre>
| + | |
| − | "dns_prefetching": {
| + | |
| − | "enabled": false,
| + | |
| − | </pre>
| + | |
| − | | + | |
| − | == Start-up DNS queries ==
| + | |
| − | | + | |
| − | When Chrome starts it queries for several non-existing hostnames that consists of a 10 random characters, E.g.
| + | |
| − | <pre>
| + | |
| − | ttrgoiknff.mydomain.com
| + | |
| − | bxjhgftsyu.mydomain.com
| + | |
| − | yokjbjiagd.mydomain.com
| + | |
| − | </pre>
| + | |
| − | | + | |
| − | This is used to determine if your ISP is hijacking NXDOMAIN results [http://www.google.com/support/forum/p/Chrome/thread?tid=3511015c72a7b314&hl=en].
| + | |
| − | | + | |
| − | == History ==
| + | |
| − | Chrome stores the history of visited sites in a file named History. This files uses the [[SQLite database format]].
| + | |
| − | | + | |
| − | === Timestamps ===
| + | |
| − | The History file uses the following timestamps.
| + | |
| − | | + | |
| − | ==== visits.visit_time ====
| + | |
| − | | + | |
| − | The visit date and time values in the visit table are in (the number of) microseconds since January 1, 1601 UTC
| + | |
| − | | + | |
| − | Some Python code to do the conversion into human readable format:
| + | |
| − | <pre>
| + | |
| − | date_string = datetime.datetime( 1601, 1, 1 )
| + | |
| − | + datetime.timedelta( microseconds=timestamp )
| + | |
| − | </pre>
| + | |
| − | | + | |
| − | Note that this timestamp is not the same as a Windows filetime which is (the number of) 100 nanoseconds since January 1, 1601 UTC
| + | |
| − | | + | |
| − | ==== downloads.start_time ====
| + | |
| − | | + | |
| − | The start date and time values in the downloads table are in (the number of) seconds since January 1, 1970 UTC
| + | |
| − | | + | |
| − | Some Python code to do the conversion into human readable format:
| + | |
| − | <pre>
| + | |
| − | date_string = datetime.datetime( 1970, 1, 1 )
| + | |
| − | + datetime.timedelta( seconds=timestamp )
