Redirect User to a specified page when typing url of a folder

Hello,

I organise my site pages as below : 

SitePages

Folder1

Page1

Page 2

Folder2

Page1

Page2

Page3

Page4

.....

to access to the page Page1 in folder 2 , i have to go to : http://mySite/SitePages/Folder2/Page1.aspx.

My question is  : there is a solution to redirect the user to my page Page1 when he type : http://mySite/SitePages/Folder2 ?

i hope i was clear, and sorry for my bad english.

Thanks.
