Refer to the following points to learn more about the HTTP routes:

• If you host multiple Odoo databases on the same instance then different database might running on different domains. In that case you can use --db-filter options or you can use the dbfilter_from_header module from https://github.com/OCA/server-tools, which helps you filter database based on domain. This module was not migrated to version 12 at the time of writing this book, but by the time of publication, it probably will have been.
• To see how using templates makes modularity possible, check out the Modifying an existing handler recipe later in the chapter.
