Use the multi-site feature to install in the secondary directory of the website
Since installed in a secondary directory, there is no need to parse a new domain name.This is the translation of the provided JSON content: 'At this moment, accessing the second-level directory's website can enter the front desk, but it cannot enter the back desk through this method. To enter the back desk of the second-level directory, you must click the 'Access Back Desk' button in the Multi-site Management here.'Therefore, the operation of background login is different from the ordinary installation in the root directory.
Installing to a secondary directory does not require domain resolution, and in this case, there is no need to set up pseudo-static rules for the secondary domain site either; it will be handled automatically.
