ASP stored the session ID, default setting of Safari is block cookies(From third parties and adertisers)

Hey all,
AS ASP stored the session ID in a cookie (the variables themselves remain on the server), I used Domain Masking to Redirect the URL.
However the default of setting in Safari is Block cookies--From third parties and advertisers, which in result, my site does not work properly.
How can I change the Setting of the Safari browsers to be "Never" block cookies or something else through the code behind.

Thanks,T
