I simply want to rewrite a URL like http://www.domain.com/2010 which actually opens something like http://www.domain.com/page.aspx. Since that's not a complex rewrite requiring wildcard mapping, I decided to use urlMappings section in my web.config file.
All worked fine for 95% of users. However there is a strange issue: when users behind strict security rules & firewalls (bank employees in my case) try to view the page, they get a download dialog box, which is trying to download a file named "2010".
I have no further information about the system of the users (ie. browsers, security apps, restrictions applied at enterprise level...).
Do you have any idea about the source of that problem? Thank you.
