@sethttpheader no effect

I want to set the “Expires” of the httpheader to 0 so that pages can expires when user click “go back” on the IE.

I place a field Computed on the form with @dethttpheader(“Expires”,0) in it. However it takes no effect. users can still go back without expiring warning.

I have tested it seveal times and read the related topics on the forum. Still can’t find the answer

Does antbody know ?

Thanks in advance!

Header field values are text:

@SetHTTPHeader(“Fieldname”,“Value”)

Thanks Stan. but it doesn’t work no matter what I use @sethttpheader(“Expires”;“0”) or @sethttpheader(“Expires”;0)

it seems that the server just sending the responce as its own way.

Have you looked at the HTTP response header?
