how to find sub-domain?
 

I created a sub-domain, say: www2_mine_com,
http : / / ww2_mine_com/index_html is in directory
public_html/www2/index.html.

I am wondering how http server finds the page: which (symlink) file contains redirection info?

thx

subdomain, http and redirection
 

for browser to:
http (://) subdomain_mydomain_com/index.html

the page is actually in directory:
public_html/subdomain/index.html

I am wondering how http server finds the page, there must be a redirection file (maybe symlink file), but wher it is?

thx

how to know if a directory is normal one or subdomain?
 

there are 2 directiries under public_html directory:

public_html/images
public_html/pictures

"images" is a normal directory (uploaded by ftp) and "pictures" is a subdomain (created in cPanel).

if using cpanel, I know "pictures" is subdomain because it is displayed as subdomain in cpanel.

but:
How can I know a directory is subdomain programmatically? I mean, kowning it from C++ program, I am sure that there must be info about subdomain stored in some files, do you know the info files? where are they?

If I know the info files, i may read subdomian info from them by c++.

you need to make a virtual host

Merged a few similar threads together.

if you are running apache then look in the httpd.conf file for a virtualhost section
