Some 8 months ago, I started saving user options in my cookie; as user changed options, my php code change the cookie value. I work normally with Camino, but verify with Firefox (V. 3). An associate with a newer MacBook Pro, with Firefox V. 5, tried my site and reported that the option change 'did not take'. I tried using my V.3, and everything worked. Realizing that I should be on V. 6, I upgraded today, and myself verified that the 'new' cookie value is NOT being saved. Rather, a second cookie is being created but with WITH NO VALUE. Result: old cookie has old option value; new cookie has no value. I tried also with Safari, and got this same result. So, there must be a way to update a cookie value, just unknown to me. Please advise as to new/proper header(s) to send from my server to change cookie value.

Make sure that the cookies are created for the proper path.

A good place to ask questions and advice about web development is at the mozillaZine Web Development/Standards Evangelism forum.
The helpers at that forum are more knowledgeable about web development issues.
You need to register at the mozillaZine forum site in order to post at that forum.

Same PHP code generates both cookies, so all cookie parameters are identical; only changes are to value and expiration time. However, before posting my query, I did check (using in-browser javascript 'alert') and the old/new names, paths and other params are identical.
