php - maintenance mode on root avoid addon domains -

problem 1

it little difficult have 3+ addon domain , folders in root.. example

www/index.php   rootsite.com www/example.com/index.php example.com www/example2.com/index.php example2.com 

remember above example.com , example2.com folders inside mains

so when put rootsite.com maintenance mode.. using

rewriteengine on rewritebase / rewritecond %{remote_addr} !^11\.111\.111\.111 rewritecond %{request_uri} !^/maintenance\.html$ rewriterule ^(.*)$ http://rootsite.com/maintenance.html [r=307,l] 

it diverst example.com example1.com root.com/maintanance.html kindly tell way avoid making example sites non maintanance mode.. not want .htaccess rules on root affect addon domain (in folders)

problem 2

also other thing need pre made count down timer (in hours:min:sec) when site goes under maintenance mode... after countdown ends must divert rootsite.com.... can change .htaccess? mean when count down ends must change rule of .htaccess remove rule of maintanance mode.

problem 1

.htaccess applies physical subdirectories, regardless of virtual host.

solution 1:

create www/example.com/.htaccess containing:

rewriteengine on 

this override rewriting rules in higher-level directories.

solution 2:

don't put maintenance rewriting rules in .htaccess. instead, put them directly in <virtualhost> section in configuration file of root site.

problem 2

put condition on rule based on current date using date variables. e.g.

rewritecond %{time_year}-%{time_mon}-%{time_day}t%{time_hour} \             2011-02-18t(09|1.|20)   # 9 9 pm today 

this constructs string of current date , hour time_* variables, e.g. 2011-02-18t15 (this prefix of date in iso format). can construct longer string including minutes , seconds if need granularity.

the regex matches number range 9 20, match times 09:00:00 20:59:59, i.e., 9 9 pm.

add condition next other 2 rewritecond directives , rule active in time range.
