Synchronize no-cache headers. This reverses revision 13940 because no-cahce headers were already being sent in displayHtmlHeader() for left_main.php and right_main.php (the tracker referred to in that revision only applies to SquirrelMail 1.4.x). git-svn-id: https://svn.code.sf.net/p/squirrelmail/code/trunk/squirrelmail@13945 7612ce4b-ef26-0410-bec9-ea0150e637f0
Special folders that are turned off get saved in user prefs as "none" (SMPREF_NONE), so we need to test for that case when autocreating. Commit number 12315 (squirrelmail.svn.sourceforge.net/viewvc/squirrelmail?view=rev&revision=12315) was a little over-zealous in this one place. (#1972177) git-svn-id: https://svn.code.sf.net/p/squirrelmail/code/trunk/squirrelmail@13494 7612ce4b-ef26-0410-bec9-ea0150e637f0
