Just wanted to thank you for a great explanation from a basic level of the benefits and pros of working with xDebug. I wish I would have learned to use this years ago

Comment on PHP: Remote IP + Load Balancer by Brett

Brett — Wed, 16 Dec 2009 15:58:14 +0000

It depends on the load balancer. Netscaler does more than balance the load, it acts as an http proxy (or any web-specific protocol) for your client connections. It optimizes TCP traffic as to keep the TCP traffic (syn/ack handshakes etc) from taking resources on your Web servers. As such, it makes the connection to your web servers behind it and, thus, $_SERVER['REMOTE_ADDR'] always returns the ip address of the Netscaler. The Netscaler sends an additional HTTP header (I believe) to indicate where the request initiated. The method above uses this information to get the remote IP. I will note that it will also work when the Web server is not behind a Netscaler because it falls through various optional headers and uses more typical header values as a fallback. What we have now is a "standard" load balancer that simply routes the inbound packets (NAT.) The incoming packet source IP is maintained and no special method for getting the remote address is required. Most likely, your load balanced solution will fall into this category. If so, you will not need to change anything. Finally, this method could be modified to be a "standard" PHP function in a non-codeigniter implementation. Here is a link to another blog to demonstrate.

We have an intranet on LAMP, and planning for a Load Balancing architecture.
We donot have Codeigniter here and we too log the client IP address as of now by using: “$_SERVER['REMOTE_ADDR']“. It will be useful if you may throw some light on how we can get still get the Client IP in the LoabBalancer scenario.

Thanks

Comment on Ruby on Rails is cool by bretticus

I have yet to follow up on ROR. I played with it one day and later found I have NO TIME apparently to do more research. On a side note, I do know the labs department of the company I work for is using ROR to “tack up” concept Websites quickly. The developers then do the real work in java. Also, ROR had (has?) a major security flaw. It was dealt with quickly (howbeit…strangely.) All in all, I still need to play with ROR to see if I could ever consider using it in a production environment (I’ll stick with tried-and-true PHP for now…yes, yes…I know PHP has had a security issue or two in its time as well.)

I think it looks nice, though personalization with a skin would be my vote. Say hi to Steph for me! (this is Alicia)
