I need to get SSI working in IIS 5.1 -- the version that ships with XP.
My pages work fine on the ISP site, but the local version does not
display any SSI content.

I've examind the IIS Properties for the Default Web Site (my site), and
under Application Configuration | Default Application | Configuration,
ssinc.dll is the executable path for extensions.STM, .SHTML, and .SHTM,
with GET and POST the verbs.

I notice that I cannot add any additional extensions (like HTML) -- the
OK button stays greyed out.

Any chance of getting this working?
