In both cFolders and cProjects, you have the option of using a browser plug-in (java-based applet), which enables user-friendly file handling when checking documents in and out. Without this, files can still be edited using plain HTML, however, this is not as easy to use.
Using the applet does not change the security level on the server, because the applet only automates some HTTP calls. However, the end user must accept a signed applet on the front end. This is a zero-footprint step that must be confirmed for each browser session, unless the user accepts the digital certificate. For more information, see Plug-In Security.
