Enable register_globals in one virtual host

one of my client wanna install prestashops.

They want register globals off and session autostart setting to off.

Those setting only applied to their store only, not affect whole setting.

Because I have setting to httpd.conf I just add two lines :

<VirtualHost >
DocumentRoot /home/clientname/public_html/store
php_flag register_globals off
php_value session.auto_start 0

Yes, master value leave intact and this setting only available to

To verifiy it you can use phpinfo().

Learning .htaccess : 101 way

My friend got suprised when he see login page on phpmyadmin. It’s not usual form for login as he used to login for.

Well, another postfixadmin admin page also show login page. He ask  me to list all tutorial around .htaccess to show for his learning study.

Like I did in Cisco Lab Topology, Cisco Resources or Ipfw Resources , I think I search google too for existing tutorial, Learning On Demand rules :-)

Here’s what I found so far :

  1. .htaccess Tips and Tricks  part I creating this hidden file in the root folder (or any sub folder) of your website, it is possible to set/unset almost all the server directives that can be set in the apache main configuration file. And these changes will take effect only for the root folder in which you created the file and its sub folders. Thus .htaccess file plays an important role in providing fine-grained control to an individual managing a website without giving blanket control of the web server.
  2. .htaccess Tips and Tricks  part II, the arcane mysteries of URL rewriting.
  3. Hotlink test for image, find out if your .htaccess protect your images.
  4. Setting Up .htaccess, htaccess can be used in co-ordination with the Apache web server to password protect certain files and directories on your web server.
  5. .htaccess file generator, create .htaccess file online.
  6. How to Configure Your Website Using Htaccess in Linux with Apache, .htaccess files (or "distributed configuration files") provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.
  7. HOWTO php.ini overrides with .htaccess,
    in smaller environments where there are only a few developers and a single product there is seldom a need for different values of a php.ini setting. however, depending on how esoteric some of the developers in your group are, or how many projects you have going simultaneously, or how many devs you have working on the same box or you have production and development running on the same box or whatever; you may at some point find a need to have different values for certain php.ini settings for different environments hosted on a single server. the good news is, if youre running apache, php has integrated support for this need.
    .htaccess overrides are especially attractive in shared hosting environments where there is a high likelihood different clients will want different settings for php.ini directives.

Check  again using netcraft or untroubled

Change Solaris 10 to other, like GWS/2.1 ( google engine? hehehehe) or girlfriend name :-)
