Can a website subdirectory be served by a different web server?

Suppose I have a website hosted at the url:

http://www.mysite.com/

Say this is hosted by hosting provider "A".

Now, I want to host a subdirectory within this site at another h开发者_Python百科ost:

http://www.mysite.com/blog/

...say I host this with hosting provider "B". So all the pages under this site would be at a completely different data center.

Is this configuration possible?

If you can configure a reverse proxy... then yes.

Apache mod_proxy

IIS reverse proxy <= is is a codeproject solution and may not have support. You can probably find many more if you just search for reverse proxy.

If you are using IIS7 (Vista, Windows 7, Server 2008) you may use the HTTP Redirect feature that is built in.

Yes, entirely possible.

Recently I came across this exact problem, using IIS. For our solution we used ISAPI_Rewrite 3.

You can use a simple directive in IIS with ISAPI_Rewrite 3 and the RewriteProxy directive

If you are using Apache mod proxy will work, (mentioned already here). Unfortunately there's no equivalent of RewriteProxy in Apache mod rewrite.

One caveat of this solution we had was to make some rewrite rules to handle the new url's to blog posts.

You'll need a sqiud server in front of both apaches for optimal results. All the requests will come to the squid instance, which will route it to the right apache based on request path.

Both apaches will have to be configured for that domain. DNS A record must point to the Squid instance.

I beleive following is the best way to handle the situation:

(a) Create a sub-domain mapping withthe sub-directories. (b) Map this sub-domain with a new IP (New hosting server)

Isn't it clean and simple?
