The limitations may be scattered (can't prototype with Sharepoint, can't download third party database apps and test them if they rely on windows authentication, issues prototyping with certain versions of SSRS), but many professional developers will likely hit a wall somewhere.

Hi Kevin

from Charles link

"Windows Authentication is a low cost authentication solution for internal Web sites."

what authentication would be best used for public facing web sites ?

Authentication is an area I find confusing. can you (or anyone else) point me at a good explanation.

Thanks
