SMSc3.5: Disable SEO feature disables SEM page also

Project: SMSc3.5
Test Env: yell-dev-mms1

Steps:
1. Log into SMSc app using valid credentials (BpId = gptest15)
2. Goto "Business Function Content" tab and click "Disable SEO Pages" check box.

Expected:
All the SEO pages (Home Page, BF Content page, PP page and COU page) must get disabled.

Actual:
Along with SEO page, the SEM page (http://yell-dev-mms1.ri.thesearchagency.com/sites/www.gptest15.com/sem-incometaxreading.html) also gets disabled.

Note:
This might be due the fact that in .htaccess file, all the redirects are from "root" location. Hence when a user tries to access SEM page, the rule
in .htaccess file redirects the user.
