Instagram OAuth 2.0授权（注册重定向URI）。 我是否也应该注册WWW。*版本的URI？

Question

I have a Web application which uses authorization via different social network account (ieInstagram). I created my account in Instagram, registered my Website URI (ie MyApplication.com) and stored secret tokens in .config file. Every time user logs in I use these tokens. Everything works fine until user visited www.MyApplication.com.

According to Instagram developers API page www.MyApplication.com and MyApplication.com are different sites. Do I have to register WWW version of my site? This requires to use another token pair. Thus, I have to check user authorization request twice!!! But it's not a normal solution.

Any ideas to do that much clear?

Answer 1

www.MyApplication.com and MyApplication.com are different.
More or less the www. is just a convention.

It's a subdomain just like app.MyApplication.com , images.Myapplication.com ect.

You wouldn't register both of them. Instead you would set up on your sever to either redirect www.MyApplication.com to MyApplication.com , or the other way around, and redirect MyApplication.com to www.MyApplication.com .

This way you only have to deal with one of them. In your case it sounds like you'd just want to redirect everything with www. to just the regular domain name.

If you're interested in the debates between www. or not.

There is an easy way to handle this your web.config. Mads Kristensen has it covered pretty well here.
