Also, for future reference it is worth noting that you need to add an
extra '\\' (or '/') to the end of the dir name when you call
cgilua.session.setsessiondir. On Windows, I did it like this:
cgilua.session.setsessiondir("C:\\Program Files\\Kepler\\session\\")
In fact, `cgilua.session.setsessiondir' checks if the last character is '/', but there is no check for '\'. I thought that Windows will accept '/' instead of '\\' in this case. Have you tried that? Tomas
