_I apologize if this is not the right place (or category) to ask these questions—Zoom’s Tier I and II Support Engineers were not able to assist and directed me to this forum. I greatly appreciate any/all assistance!_ **Background Info:** Our organization uses Zoom Team Chat for the majority of all ongoing, informal communication between-and-within departments. In particular, our Web Team frequently uses Team Chat to send hyperlinks to other departments to get feedback on recent changes and updates to pages on various websites. **Questions:** When a link is posted is within Team Chat, what specific HTML content (tags or elements) is being used to populate the “link preview” that is displayed to recipients? Related: we have noticed that the preview content seems to be cached—does that cache happen on a per-client basis or is it Zoom-wide—and is there a way to “dump the cache” or refresh, as one might do within the context of a web browser? ---

Hi @cgriffith Thank you for your patience while I worked with our Engineering team to get you some answers about this. Here is some information that might help you clarify your issues: > 1. When a link is posted within Team Chat, what specific HTML content is being used to populate the “link preview” that is displayed to recipients? Link preview usually consists of 4 parts: a page icon picture on the left, a title on the top, a few lines of page content in the middle, and the site name at the bottom. > 1. Does that cache happen on a per-client basis or is it Zoom-wide? The cache is built up zoom-wide. Or more accurately: zoom domain-wide. > 1. Is there a way to “dump the cache” or refresh, as one might do within the context of a web browser? Unfortunately no. Our preview cache gets refreshed automatically after 24 hours. But it’s not under the direct control of the chat user. I hope this information is helpful and again, thanks so much for your patience. Best, Elisa ---

Can you provide some information about link to file in chat? I can see that if a text message contains http:// or https:// prefix it becomes a link, but if it contains file:// it remains plain text.
