Make a folder redirect

[samiles]

Hello,

I want to make a folder on my website redirect to another one...

I know I could just add a meta redirect tag to the index.html file on the folder... but this is then slow, and I know of websites that don't use this, and just make the folder redirect.

I have heard about a 302 redirect... is this what I need?

I am running a linux server and have PHP, Python etc.

Thank you for your help,

Sam
