How add html or create .lp file

[admin]

You can upload .html the same way as you upload .lp files (FTP apps user). Note that only .lp files are password-protected. Other resources like .html, .css, .js etc are served without password check. You can also put HTML into .lp, see apps documentation for some examples if you need to have both HTML and Lua in a single .lp file.
