Redirect page causes 404 status

When I woke up, I still didn't feel as good as yesterday.

Since it's Sunday, I decided not to push myself too hard and stopped updating the craft store.

I've been immersed in handicraft work and haven't had much web-related information lately, so I write like a web guy.

I omitted the explanation yesterday in "The redirect page was in a 404 state!", but this is also essential for SEO measures.
It may seem difficult, but with Joomla it's easy if you have some knowledge.
If you search for the detailed setting method, you can find an explanation that is easier to understand, so I will omit it.

Initially, there is 'htaccess' in the joomla package, so configure it for your site.
If you make a mistake in the setting method or meaning of the settings for your own site, you will receive many redirects, but in such a case, either go back to the original settings and modify them to the correct settings, or give up. It is important to learn from experience when setting mistakes occur.

By the way, this time, Alaudae.JP has changed the file and folder names to make the content easier to understand.

Old URL link 'example.JP'/'Me'/'You'/'Is it.html'

New URL link 'example.JP'/'Me'/'Who'/'Is it.html'

and the new URL link, you can change the 'you' folder to the 'who' folder and set up a redirect with 'htaccess', but the old URL link I realized later (yesterday) that if you change the folders and files under the 'you' folder in 'we' with a new URL link, you have to redirect them within the new URL link.

Old URL link 'example.JP'/'you'/'who'/'we'/'Stranger.html'

New URL link 'example.JP'/'me'/'who'/'Stranger.html'

If you want to,

Old URL link 'example.JP'/'you'/'who'/'we'/'Stranger.html'

New URL link 1 'example.JP'/'me'/'who'/'we'/'Stranger.html'

After setting the redirect

New URL link 2 'example.JP'/'me'/'who'/'Stranger.html'

It seems to redirect to again.
Redirection can be set as standard in joomla and 'htaccess' is not required.
However, if you are familiar with this, you should probably be able to complete the settings within htaccess.

I used files and folders with Japanese names, but they can actually be used in Joomla.
It's like a Punycode conversion function for Japanese domains.
However, I think that using files and folders with Japanese names would be troublesome to fix in case of a problem and would require some knowledge, so Alaudae.JP does not use files or folders with Japanese names except for Japanese domains.

I'm not sure about the explanation, but I have actually confirmed that the old URL displayed in Google and Yahoo! search results will display a 404 before the correction, but will link to the new URL after the correction.

I would like to explain in more detail, but I don't have the ability to write it down, and writing detailed explanations would take several days.
So these are my notes.
It's a personal miscellaneous notebook so you won't be in trouble if you forget something.
