Partial html compression possible?
Posted: Sat Oct 09, 2021 9:48 am
Hello!
I have 15 html files, all of which uses a lot of JS linked locally and every html has different <body> (each file has about 100kB of <body>). I won't be able to store it inside ESP32 Flash without compression. I converted index.html into single file using https://github.com/remy/inliner and then to char array (about 1.5MB) and everything works fine when I use:
When I gzip it and send using:
also everything works fine.
And here's my question: If I cut out <body> part from index.html and save it in another file, can I compress them separately and send them to browser? Because JS and CSS part is common for all html files I would save enormous amount of Flash space. If that appoach is correct which functions should I use? Thanks!
