2 WEB Servers 1 Domain

jcyph

Hello,

I have two webservers having two different IP adresses and location. I have only one domain name (e.g. mydomain.com) and is redirected to either webservers.

I'm not sure what will happen to the php page if it start processing. The page is only used for user input validations and forwarding mails after success.

The scenario is this, if a user logs to mydomain.com the DNS forward to either available webserver, lets say WEBSERVER 1 . After serving the page to the user, the user enters to another page, again the DNS forward to either available webserver, lets say WEBSERVER 2 .

What if the page has webserver scripts-PHP? Let say Data Entry Form (action = POST). Will there be any conflicts once the user clicks on the submit button? What are these? :rolleyes:

Please advice....
🙂 jcyph 🙂

P.S.
I'm not allowed to
1. Changing the URL to the actual IP add
2. Using of frames

Why are we using 2Servers and the other thing is are they yours if so. Why not set up a Raid System

You shouldn't have any problems, since http is stateless. Basically, WEBSERVER2 won't care that it didn't serve the first page, only that it just got a form submission.

Now, if you're using sessions you could will have problems. A solution is to set up the session save path to be on one or the other system, or to save session data in a database accessible to both machines.

Well, is the PHP Post form a stateless?

Cause i need to be carefull. I never thought of these things before that there will be conflict to come-up. Before I only maintain single web server, but for certain reasons we need to set a back-up or another one to accommodate everything as much as possible.

Now, if you're using sessions you could will have problems.

As to your suggestion, do you have any further info on how to facilitate these things?

Also, how do I get the IP Add of the user who just submit the form or who have just access the page?

RAID SYSTEM????
These two servers are SHARED and hosted respectively...

Thanks in advance
