The code below is from a ubiquitous example of how to run a webserver on a Raspberry Pi Pico W. I'm trying to use pieces of it to serve up a web page, but my page includes a lot of HTML formatting and is much larger, about 7 KB. When it runs it seems to only serve up about half of my HTML code; if I remove much (but not all) of the formatting code, it works.
In the example, the HTML part is very small:
html = """<!DOCTYPE html>
<html>
<head> <title>Pico W</title> </head>
<body> <h1>Pico W</h1>
<p>%s</p>
</body>
</html>
"""
Does anyone know if there is a limitation to the size of a web page that can be served up, and if there is any way to get around it?
