2. Check or uncheck to enable or disable listening for incoming connections.
3. Opens component page in default browser. Button is inactive if server/listener isn't started.
4. Limit access to component by setting the allowed IP address. Connections initiated from other addresses will be discarded. Setting this to 0.0.0.0 allows all connections.
5. Limit access to component by defining a login/password pair. Untick to disable passwords.
6. Built-in file browser can be limited to certain paths of your file system. It is useful to simplify the browsing process or hide your secret files from prying eyes. For example, setting Allowed paths to d:\music|c:\temp\music|e:\ permits browsing only in these three file system branches.
7. You can specify additional file extensions to be treated as playable files by built-in file browser. It is required for opening archives containing playable files.
8. Ignore files with specific extensions in file browser.
9. Urls of specified protocols are allowed to be enqueued by Browse command. Enables enqueueing of urls handled by 3rd party components like foo_youtube (3dydfy protocol). Suggested value setting: http|https
10. Removes all files which foobar2000 core considers unplayable from built-in file browser.
11. Specifies path where component will look for template files. Pressing Open opens specified or default directory in Explorer. If not sure, leave it blank.
12. Enables gzip compression of component output. Enabling it is usually harmless and quite beneficial as component generates a lot of text which is very compressible. Disable if you are using some funky browser.
13. Enables logging of component access data to foobar2000 console. Useful for debugging etc.
14. Adds "Stop after queue" item in Playback menu. It works exactly as it's named, stops playback when end of playback queue is reached.
