iis 7.5 using generic 500 error (classic ASP)

view full story

http://serverfault.com – I've defined a custom error page for all the 500 subcodes in IIS, but some errors seem to be using the generic 500 file (and for some reason server.getlasterror gives me an empty object when this happens, unlike for a 500.100 or other specific errors in which server.getlasterror gives detailed information about the problem that I can send me in an email). Is IIS 7.5 missing some error codes and using generic 500 for those? (HowTos)
