UrlReferrer shows a value with hyperlink but null with Response.Redirect

I am redirecting between two pages, when I use a hyperlink I get the Page1 in the 开发者_Python百科UrlReferrer field, but using Response.Redirect gives it null.

AFAIK both of them act similarly for a redirection. Can anyone help me understand this behaviour?

Thanks for the help!

did you try another computer? or maybe just a new blank solution?

for me it works great.
