Hello,

I'm using your library and I'm enjoying it so far. Thanks!

I have a question, I have a string stored in progmem, what's the best way to format it and print to the webserver?
I tried with server.printf() but seems to be limited to 128 chars

Example of what I mean

P(message) = "Hello %s!";
server.printP(message, "Ricardo");

This is a limitation of the Arduino library. Try doing the formatting as a series of prints instead of trying to build a string in RAM and output it. This was designed for a low-RAM 8-bit processor back in 2010, and I certainly don't recommend using this library for anything these days with much better web server systems available on hardware like the ESP32 or Raspberry Pi.

I'll be using Arduino MEGA, so it's not like ESP32 hardware.
I really liked your library and it's not much oversized.
Anyways, which library would you recommend instead of yours?
