txforward, a transparent reverse proxing extension


Download package (Current version 1.06):

From version 1.02, it is directly integrated into PHP pecl's cvs.
To install it, just type:
pecl install txforward

Or directly download the source and run the manual configuration steps below:


cvs -d :pserver:cvsread@cvs.php.net:/repository/pecl/txforward checkout txforward

Configuration:

phpize
./configure --enable-txforward
make
make install
Then edit your php.ini to load the txforward.so module
extension=txforward.so
If you're chaining proxies, you can specify proxy depth in your php.ini.
For exemple for 3 chained proxies:

        CLIENTS <-> RPROXY1 <-> RPROXY2 <-> RPROXY3 <-> WEBSERVER
depth      4           3           2           1           0

Just add:
        [txforward]
        txforward.depth = 4
This will look for the IP that is in position 4 behind the 3 chained proxies.

In case of misconfiguration,  it always falls back to a depth of 0.
