HTTP server response headers are not cleared between fetches

[anecdata]

This issue will probably have to get moved. I'm seeing some interesting behavior with web server response headers, not sure where to put the issue. Somewhere, I don't think it's here in ESP32SPI, but then must be either NINA FW or the depths of CP.

Headers not served by the current server are delivered back to the client. I see this on every HEAD or GET from virtually any site after the first site. After pulling a couple of pages from disparate sources, an accumulation of unique headers from prior server responses are presented to the client in response.headers along with the correct headers from the current site.

Clearing the response in the client using response = None does not clear the headers, the accumulated set of headers is still returned on subsequent calls.

Code and output in a Gist here:

This happens with fetches using either adafruit_esp32spi_wifimanager.py or using adafruit_esp32spi_requests.py directly.

Thanks @anecdata. I just tried it on my PyPortal and am seeing the same results as you.
