Webserver and pascal script problem

Hello everybody. I have a problem with one of my small programs.
Basically a web server that interprets pascal code through pascal
script.
The example is trivial, but when I use the program massively the
memory occupied goes up and is not freed until the program closes.
Tested with ubuntu and mac os. The problem is replicated on both.
To replicate the problem, download the attached file and unzip it.
Then compile the project

laz_https_server_test_ps/pkg/laz_http_server.lpi

Then compile the console to stress the program

laz_https_server_test_ps/console/pkg/console.lpi (requires installed
indy)

Both executables are created in

laz_https_server_test_ps/bin/

Now run both programs (laz_http_server from the terminal), open the
activity monitor and identify the laz_http_server line and monitor the
memory occupied.
Then move to the console that you have compiled and press the only
checkbox you find and successively the button you find in the top
left.

Basically the console will take care of cyclically querying the
laz_http_server program. When you want to block it, just uncheck the
checkbox component.

I didn't test it but I guess the problem is that the program doesn't
release resources when not needed.  Maybe you're creating a new
conexion object everytime a request is made and then forget to release
it (or to reuse it?).
