New in latest Tiny PXE Server version : some files served over the built-in HTTP daemon such as files with extension PHP, VBS and PY can be dynamically processed on the server side and not simply sent back as text/html files.
This gives one the ability to implement a logic on the server side thru php, vbscript or python, including parameters in the URL.
Other engines could be added later on such as node.js, perl, …
Example of ipxe script file on the client side (more reading here).
chain http://${next-server}/boot.php?param1=value1&param2=value2
Example of a boot.php file server side.
<!--?php //use $argv[1], $argv[2], etc to retrieve url parameters
echo "#!ipxe\n";
echo "kernel ${boot-url}/wimboot\n";
echo "initrd ${boot-url}/bootmgr bootmgr\n";
echo "initrd ${boot-url}/boot/BCD BCD\n";
echo "initrd ${boot-url}/Boot/boot.sdi boot.sdi\n";
echo "initrd ${boot-url}/sources/boot.wim boot.wim\n";
echo "boot\n";
