P4Web in Standard mode runs on your local machine and allows you to manage files in your Perforce workspace. (Compare this to Viewer mode.)
With a P4Web running in Standard mode, you can use your Web browser to run Perforce commands and work with files. P4Web can sync files, open files for add, edit, delete, etc., resolve files, submit changelists, and so forth. In Standard mode, P4Web must be started up and running on the machine where your workspace resides. For information on starting up in Standard mode, see How to Start P4Web.
Only you can use your P4Web in Standard mode; access to it is protected by your Perforce password. For more information, see Passwords and P4Web.
