unsubscribe button url problem

ZenCart Version 1.3.5 NEW INSTALLATION

browsing as a Guest [anonymous] the IE6+ and IE7beta browser does this:
both are set to allow this site as Trusted Site, Privacy Setting, and Popups.

clicking Newsletter Unsubscribe in Information SideBox goes to this url -

https://www.somedomain.com[b]/folder1/subfolder2/[/b]index.php?main_page=unsubscribe

page displays properly

upon clicking "unsubscribe" button on the above page the url address does this

https://www.somedomain.com[b]/folder1/subfolder2/folder1/subfolder2/[/b]index.php?main_page=account_newsletters

which is server page not found due to doubling of the folder path above

if I cut one of the /folder1/subfolder2/ out of the browser's address string then click go it does this again:

https://www.somedomain.com[b]/folder1/subfolder2/folder1/subfolder2/[/b]index.php?main_page=login

            which is server page not found due to doubling of the folder path above

i believe it should be going to the zencart signup/login page as indicated in the path it tries to go to in the above address.

i'm having trouble finding which file may be causing this path problem to occur.

any suggestions or recommendations will be greatly appreciated.

thank you.

Got IT! can't set IIS to require secure on entire catalog

and configuration.php's set to

HTTP_SERVER ```
https://www.somedomain.com/folder1/subfolder2/

and HTTP_CATALOG_SERVER ```
https://www.somedomain.com

This causes the double /folder1/subfolder2/ on the Newsletter Unsubscribe path.

Thanks sorry for the premature post.
