On a site for users, I have to add a module that shows to the user, upon entering, site conditions in a separate window, and the user must accept the conditions show to follow and if he refuses, can not continue.
My question is, how I can develop this module in the presentation layer? Is there some control of either C # aspx.net or third parties.
The module must support any extention of documents (pdf, doc, txt ...) including images (jpg, bmp ...)
Thanks for your help
