- Is there a way to set different favicons on different sites on the same Liferay instance?
- Liferay Portal 6.2
- Liferay DXP 7.0+
The easiest, supported and recommended approach would be to create one theme for each site and then apply it to the pages of that site only.
For a more complex approach, you can refer to this blog post as a starting point: Overriding the Favicon in DXP. In that case, the code that the developer shared shall be readapted in a way that runs conditionally when navigating to a certain URL path.
