Any difference between Mod ReWrite and real subdomains

[Hypertext]

I don't know, I prefer it cleaner. using images.x.com instead of x.com/images

is there any real difference? if I just reroute a few subdomains in the root.

mod_rewrite and subdomains.. are two different things.

A subdomain is really just a slave zone of the master zone.

example.com is a subdomain of com
www.example.com is a domain of example.com

mod_rewrite is a totally different thing, not dealing with DNS at all. mod_rewrite is just Apache's rewrite engine.

It just modifies a URL's appearence, not the actual serving of a domain..

Hmm. It's just I'm going to be doing a lot of stuff in SVN and don't know if it's worth the hassle of keep changing servers. Maybe I'll just upload my tools on a subdomain (trac, pb, svn, etc..) and then use mod rewrite for my other folders whichi will be portrayed as subdomains.

Nice plugin.

I don't think you have a clue what you are on about, you are really mixed up..

Explain.

the rewrite module is commonly used to capture a part of a url for example

http://yoursite.com/go/pie

and then place it behind the scenes for example, in front of .php . That would then make the server load pie.php and display it whilst the URL remain /go/pie . I think on that basis was the reason as to why caleb thought you were confused between the 2.

I may be wrong, not knowing its full potential - but I hope you get the jist of it.

mod_rewrite allows for modification of the URL, not seen by the client.

They type: http://www.example.com/test and they get -> /test.php

They type: http://example.com and they get a 301 -> http://www.example.com

They type: http://www.example.com/testing/123 they get -> /bla.php?id=$1

It is a lot more then that, those are just some simples uses of it.

Subdomains, are actual DNS zones, just like domain names, which is why they have to propagate as well.

Some common subdomains:
www.example.com
mail.example.com
ftp.example.com

Each one of those, are a slave zone added on the master zone.

EX:

When you request www.example.com

1. It finds out which DNS TLD server manages com.
2. It finds out which DNS server manages example.com
3. It finds out which DNS server manages www.example.com

When you request en.us.example.com

1. It finds out which DNS TLD server manages com.
2. It finds out which DNS server manages example.com
3. It finds out which DNS server manages us.example.com
4. It finds out which DNS server manages en.us.example.com

Very different.

If I remember you can create a subdomain using mod_rewrite, but it requires a secondary domain (not 100% sure). Ask JH as he did it previously on habbopress.

[Dentafrice]

It doesn't work on all servers though, and I think it requires wildcard catch all.

Yeh I don't think it's a surefire solution. You're better off either setting up proper subdomains, or just leaving as a directory.

[Dentafrice]

Just read up on it, it is impossible without your host enabling wildcard domains. Then catching the domain with htaccess and rewriting it.
