Redirect file with a bot filter.

Task: write a simple redirect from a domain to the desired address, while diverting bots to the side. The domain folders are empty and will not be filled. I will provide a list of bot user agents. Price negotiable. It does not matter to me what kind of redirect it will be, the main thing is that it diverts bots and works fast, without a noticeable delay. I am waiting for your proposals and implementation options. I do not place any special requirements on the contractor. Deadline 1 day.
