htaccess reading files from folder (web alias)

i have in ROOT folders root_public, root_about, root_maps

and i need to show it to this sample:

• domain.com <- everything from _public
• domain.com/about AND domain.com/about/ 开发者_运维知识库<- everything from _about
• domain.com/maps AND domain.com/maps/ <- everything from _maps

but i don't know, what i will do with root_public\maps .. it could be problem. so how i can resolve this problem? because i need this structure. and how i can do this?

i am using:

Options +FollowSymlinks
RewriteEngine on
RewriteRule ^(.*)$ _public/$1 [NC]

this to read everything from file _public but i don't know, how to do subfolders!

thank you!

Based on your question, I am assuming you have a directory structure that looks like:

/your/document/root/_public
/your/document/root/_about
/your/document/root/_maps

...where the Apache DocumentRoot is /your/document/root.

The following would work, though I'm sure there are neater solutions.

# add trailing slash to domain.com/about and domain.com/maps
RewriteRule ^/(about|maps)$ /$1/

# rewrite domain.com/about/something to /_about/something
RewriteRule ^/(about|maps)/(.*) /_$1/$2

# rewrite anything that doesn't start about/ or maps/ to _public
RewriteCond %{REQUEST_URI} !^/(about|maps)/
RewriteRule ^/(.*) /_public/$1
