Hi all,
Thanks for all the tests!
BTW, if you wonder why the demo server feels a bit 'sluggish', it's because it runs on an prehistoric 500MHz VIA CPU in my basement
About the MIME type: elibsrv returns files using the mimetype "application/epub+zip". I think (?) this is the right one to use, right?
About browsers that do not want to open files: I don't really know what exactly every browser base its decision on.. I tested only using Firefox + EPUBReader on my Linux desktop, and it works fine.
I will see what I can do to make it easier on other browsers, too.
