Redirection / Canonical Issue

[newnerd]

I have a website in HTML and has it's blog in Wordpress.

website Server header: Microsoft-IIS/8.0

X-Powered-By: ASP.NET

Now, I found that my website domain can be open both with frontslash (/) at the end of domain and without slash (/)

e.g: http://www.example.com can also be opened with http://www.example.com/////

Also, for inner pages e.g:www.example.com///////////inner-pages.html

And for blog posts same slash problem:

e.g: http://www.example.com/blog//////////my-blog-post/

Please help me to solve this slash issue. How can the urls be open without the additional garbage slashes?
