Writting a simple proxy in PHP

[Alessandro Vernet]

I would like to forward on the server side (also called "proxy" or "server-side redirect") some queries that get to my PHP script. A naive approach is to do:

print(implode("", file("http://localhost:8090" . $REQUEST_URI)));

Where http://localhost:8090 is the address I want to proxy to. But of course, this only works for simple GET requests. It does not forward headers (like Authentication), and won't work if the request is a POST.

Has anyone a suggestion on how I could implement a better proxy? I am not looking for a perfect solution. Something that would forward headers and handle posts would be good enough.

if your using apache then you should look at the ProxyPass directive - very hand,
STW or STA for more detailed info.

Jochem,

I went this route. I agree, it is much simpler than trying to hack this in PHP.

it's rather a neat way of solving the 'how to run php4 & php5 module on the same
server' problem one often encounters,

I can't take any credit though - that belongs to Rasmus Lerdorf for pointing it out
(and possibly also due to his work on Apache itself - IIRC).

regardless, nice to know you solved your problem (or at least pushed back the urgency -
I guess that one day we'll all have to let go of php4 altogether :-).
