I need to create a Customer Portal login page from an external site (outside salesforce domain).
My login page is https://www.mydomain.com/customer/login where the user can enter ID/PW Once ID/PW match from salesforce the user will be redirected to https://mycompany.force.com/portal_page/ (the actual customer portal page from salesforce)
The external site is in .NET
I would really appreciate if someone can point me to any documents, guidance, tips, API, etc. I'm a .NET developer, and it's my first time working with Salesforce.
