Using dots in HTTP request parameters

[Jonathan Daugherty]

# OAuth is designed to work with old browsers, cell phones, webtv,
# etc. Is there any reason not to use dot in parameters name? Are
# there any known compatibility or support issues (compared to using
# underscores)?

PHP has an especially pathological behavior of converting all dots in
query parameter names to underscores, so if you do go this route
you'll need code[1] to fix it.  Otherwise I think it's a fine idea. :)
