Strange to you, perhaps, but it's a very common issue.

As I said in my original reply, the problem was almost
certainly caused
by an error that you couldn't see because the display of
errors is
turned off for security reasons. The Restrict Access to Page
server
behavior uses session_start(), which must come before there
is any
output to the browser. "Output" includes new lines or
whitespace outside
PHP tags. There is almost certainly an extra line at the end
of
con1.php, which would prevent the session from starting. In
turn, that
would generate an error, resulting in your blank page.
The problem is closely related to the "headers already sent"
error
message that confuses most PHP beginners. Read about it here:
http://docs.php.net/manual/en/function.header.php
By the way, it sounds as though you are testing everything on
a remote
server, rather than testing locally before deploying to a
remote server.
That's a very bad idea, particularly if the display of errors
is turned
off. You should test files in a safe, local environment with
error
reporting turned to the highest level, and eliminate all
errors before
deploying to a live server. If you're testing locally, make
sure that
error_reporting in php.ini is set to E_ALL, and that
display_errors is on.
