Lua mg.send_file() is broken in the code cloned from github.com/civetweb/civetweb about civetweb HOT 2 OPEN

Sorry that it took a while to respond, but I really wanted to test this and could not finish before Christmas vacation.

I got me an Ubuntu 18.04.4 LTS and tested your code, but find the issue with the current head version of civetweb.
I can read the code from all three scripts.

In all 3 cases the response has exactly one byte more from the *.lp file as compared to directly loading the file.
This additional byte is the newline from the *.lp file

If this newline is removed, the result is identical.

Thank you very much for the response.

The issue you described does exist and can be easily addressed by removing a trailing whitespace from the LUA page body in mod_lua.inl:run_lsp_civetweb() and its "kepler" counterpart.

Unfortunately, the root of my problem (solved) is somewhere else. My instance of civetweb was built with ZLIB/COMPRESSION enabled, so all outgoing files larger than 1K were supposed to be automatically compressed when sent to a capable HTTP client, i.e. the one which provides the 'Accept-Encoding: gzip' header with its HTTP Get command.

All three Web browsers (Chrome, Firefox, Edge) that I've tried always define this header, but the 'curl' utility doesn't do this by default.
This is why I was getting different results while using different methods of testing: 'curl' seemed to work on large files, but the same content looked totally garbled when received by the web browser.
For my use case I simply decided to never enable the 'WITH_ZLIB' civetweb build option.

Thanks again!
