proxy server

Hi,

I have web application writing in Flex.
The clients are from different location(countries).
I want that when client try to reach the URL of application he will get it
from local server and not from the main server.
Also if possible that if there is update in main server the update will be
send to the local server at each location.

Is that possible ?
Should I use proxy server for that ?
Is the update from server can be done or I need to define some timeout that
after that the local cache on local server is removed so when user will try
to reach server it will cause to update of local server ?

Thanks

Yes. But this is not that trivial.
The easiest part is mirroring your servers to a local machine. Use
whatever works for you to do this. The hard part is getting clients to
use a geographically close server. For that you will need to return a
different IP address when a client request your hostname, depending on
where the request originates from. But this has nothing to do with
apache really...

Re: proxy server

Thanks for your quick reply.
Can you explain how do I do the mirroring part ? Is it with proxy server ?
Can you give example for one or more ?

Can't I configure in client side to use the local server and not the main
server (where I put my app)?

Thanks

Mirrororing basically means copying all the content that exists on one
server on another one. There are many different way to do this, going
from simply copying everything from one machine to another, to using
something like rsync, to using a webspider. Use what works for you.
This is however not really an apache issue.

If you have control over the clients you can configure them to use a
local server. How to do this depends on what kind of control you have.
This is however not an apache issue.
