URL preview allows users decide quickly whether to follow a link by displaying a thumbnail preview for URLs.
Thumbnails are renderings of rich metadata to point to accessible HTML resources in microblog messages in the Activity Stream.
URL preview supports the following OpenGraph metadata:
- An image representation of the resource
Metadata is obtained from the following contexts:
- User input focus (as the user types the url in the microblog message)
- Activity Stream (events about microblogs)
Configuring URL preview
Edit og-config.xml in the <dmgr_profile_root>/config/cells/<cell>/LotusConnections-config directory to configure both the oEmbed and thumbnail end-points. oEmbed returns the metadata that is associated with a URL passed in input.
- URL preview security
Restrict URLs accessible by the oEmbed and image proxy service and fine-tune the maximum number of HTTP Connections.
