The auxiliary configuration file htaccess provides many useful capabilities for configuring how a website interacts with the Apache server. Among them are such important functions as changing the character encoding and setting up redirects.
How to correctly change a website's encoding using .htaccess
One common content display problem is the browser choosing the wrong character encoding. To get rid of such errors for good and change the encoding correctly, explicitly define the required encoding using the .htaccess configuration file. Once you specify the encoding with a single line in the .htaccess settings file, you guarantee that the browser will detect it correctly, regardless of any other conditions.
Redirects in .htaccess when enabling HTTPS
Another important use of the .htaccess tool concerns migrating a website to an SSL certificate. In that case you need to redirect traffic to the new address that uses the HTTPS protocol. Find .htaccess in the site's root directory, open it with any standard editor (Notepad or Notepad++), and add one of the http-to-https redirect methods to .htaccess. It is important to note that before performing the redirect, the site should already be indexed and the so-called "merging" of mirror pages should be completed. Depending on the situation and your hosting settings, different types of redirects can be defined in .htaccess.
301/302/303 page redirects
The most frequently used redirection methods are the 301/302/303 redirects. They can be set up by editing the .htaccess file. Each redirect interacts with browsers differently, so the choice facing the webmaster must be made individually each time.
Let's look at the meaning of each of the 3 listed redirect types defined in .htaccess:
- Permanent Redirect 301. This is a message that the content previously located at this address has moved, and all old links and information have been removed. It says the URL will no longer be used and the site (page) has "moved" to a new location.
- Found 302. Tells us that the information we are looking for lives here but is temporarily unavailable for some reason. You should look for it at another address or wait.
- See Other 303. Intended for redirecting to another address when working with pages that are not meant to be refreshed repeatedly — for example, payment forms in online banking and the like.
Besides the 301/302/303 redirects, other types of redirection exist as well. To configure how your pages work with the server via the .htaccess file correctly, account for all the nuances and avoid mistakes, it is always best to consult a professional first.
