As the above poster mentioned. {REMOTE_HOST} doesn’t work. It should be {REMOTE_ADDR}.

{REMOTE_HOST} returns either the looked-up hostname of the request, if available, or NULL if it isn’t available. It doesn’t return an IP.

If you do use {REMOTE_HOST}, then you will need to use a hostname as a matching condition instead of an IP, for example:

RewriteCond %{REMOTE_HOST} ^badhost\.mydomain\.com$

Hi,

RewriteCond %{REMOTE_HOST} !^888\.888\.888\.888 is not working for me.

After some googling i’ve found a solution and I’ve changed the condition to:

RewriteCond %{REMOTE_ADDR} !^888\.888\.888\.888$

Works perfectly now! Thanks for cooking uo the rest for me. Just what I needed.

Cheers,

u put your .htaccess at your document root (where your index.html / index.jsp located)

Hi,
The configuration look simple. Thanks for that.
I have a set up where I run Apache, Tomcat connected through mod_jk connector.
My Applicaiton is deployed on Tomcat.
Where do I have to put my .htAccess file. ? I am assuming its under application root in Tomcat.

Also, If I have to switch between the maintenance mode and regular working mode, does .htAccess provide facility to do it with zero downtime. ?
If so, how do I do it. ?

Thanks,
Anand

Hi Pieter,
just add this line :

RewriteCond %{REQUEST_URI} !/picturesfolder/(.*)$

before the RewriteRule
dont forget to change «picturesfolder» for the one that applies for you.
you can also do it with your css folder, just add one more line.

Hi,

Thanks for this.

Is there any way to exclude a directory so my maintenance page can be styled with some pictures?

Best from Holland

Hello, thanks for the advice.
You can get the same result without mod_rewrite ?

My provider has not installed the mod_rewrite module.

This is pretty smooth. The only issue I have with it is that 302 is maybe not really the right response code for this situation; 503 would be more correct, but RewriteRules won’t let you use a 500-series code! The only way I’ve found around it is to redirect to a CGI script, where you can set your own return code, but I’d rather not have to use a script.

I used to use something like TC mentions – that’s nice and easy too, although it does return either 404 or 200, which are not really 100% correct either. Getting Apache to actually return a 503 for all requests turns out to be surprisingly nontrivial. The visible effect of all these different ways is likely to be the same, but I’m just looking for the “philosophically correct” way.
