On ROBLOX, the ContentFilter service causes any links to files not on one of the Roblox sites or on the trusted sites to not load. The picture on the right shows how the filter works.
Content can be formatted in many ways. All of which either point to an online file or a file saved to the client's computer. The basic structure is a protocol name, followed by
://, then a string that depends on the protocol used.
Here is a table of valid protocols:
|rbxasset||A file path.||Fetches a file from Roblox's content folders.|
|http||A website URL.||Fetches content from a website using a URL.|
|https||A website URL.||Same as http, but for pages that require https.|
|rbxhttp||A path on the Roblox website.||Fetches content from the Roblox website.|
|rbxassetid||An existing asset ID.||Fetches a user-created asset on the Roblox website.|
This starts from Roblox's content folder on the user's computer.
Any file in this folder can be used, including ones that users have added themselves. Though it will only appear for that user, since it's only on the user's computer.
Here's the location of the content folder for various operating systems:
C:\Documents and Settings\<username>\Local Settings\Application Data\RobloxVersions\<version>\content
This basically just adds the
directory to the end of ContentProvider.BaseUrl.

For example, this is a rbxassetid link that points to the justice decal by ROBLOX:
And this is its URL equivalent:
This points to the exact location of something on the internet. It only works on ROBLOX-approved sites and will raise an error if used otherwise.
The only known approved websites are those that fall under the
