Aviel Fedida's questions

I'm using Apache/2.4.10 (Win32) and I have a question about the relation between SERVER_NAME and HTTP_HOST.

I have noticed a strange(at least I think) behavior of apache, inside my httpd.conf I have:

ServerName example.com:80

Now as I tested via PHP server variables which are taken from apache.

From php(the link above):

If the script is running on a virtual host, this will be the value defined for that virtual host.

I'm not using any virtual hosts.

SERVER_NAME overridden by HTTP_HOST, for example if I will access the website via m.example.com the SERVER_NAME is overriden by the HTTP_HOST and the both be equal to the same value, now in spite it has been tested I wanted to know:

• Does apache using any virtual host without me knowing about it, here is my httpd.conf file?
• Is it PHP or apache behavior?
• Is it done automatically(the override) by PHP or Apache(at this point I don't know who's guilty)?

Edit:

• The override is done by apache, I've tested using .htaccess file, the result is that even before the variables delivered to PHP the override is done.

So the override is done by apache, the only question remain is what are the conditions for such override and more important is there a way to get or a variable that provide the ServerName value from the httpd.conf?

I have .htaccess file I'm using for testing, here is my file:

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/([a-z-]+)/?$ [NC]
RewriteRule ^ %{REQUEST_SCHEME}://%{SERVER_NAME}/?title=%1 [L]

I'm using Apache/2.4.10 (Win32) from ApacheLounge

I have the following domain and sub domain:

• example.com
• m.example.com

Both point to the same ip address, now as I expected from the above .htaccess:

if I access example.com/Article-Name/ the redirection to example.com/?title=Article-Name will be internal, I won't be able to see ?title=Article-Name on my url bar.

Here is the exception:

If I access m.example.com/Article-Name/ the redirection to m.example.com/?title=Article-Name will be external and now I see m.example.com/?title=Article-Name in my url bar.

So I was expecting the same behavior, if anyone have an idea I will be very thankful.

EDIT:

I have found a solution for the problem but I still interesting about the above problem, about the solution is to use:

RewriteRule ^ ?title=%1 [L]

Please notice: this solution is only needed for m.example.com, I really have no idea how this solution is even working, I have posted this solution because it may help finding the cause for above problem, and how this solution is even working.

EDIT 2(the full .htaccess file):

RewriteEngine On


<If "%{HTTP_HOST} = 'avielfadida.ml'">

# The actual condition is really long one so I replaced it for illustration.
RewriteCond %{HTTP_USER_AGENT} (iPhone|Blackberry|Android) [NC]

RewriteRule ^ http://m.%{HTTP_HOST}%{REQUEST_URI} [R,L]

# I have to duplicate the RewriteCond and RewriteRule both inside the <If> and <Else>
RewriteCond %{REQUEST_URI} ^/([a-z-]+)/?$ [NC]

RewriteRule ^ %{REQUEST_SCHEME}://%{HTTP_HOST}/?title=%1 [L]

# The solution(the solution is not required inside this block):
#RewriteRule ^ /?title=%1 [L]
</If>

<ElseIf "%{HTTP_HOST} = 'm.example.com'">

# I have to duplicate the RewriteCond and RewriteRule both inside the <If> and <Else>
RewriteCond %{REQUEST_URI} ^/([a-z-]+)/?$ [NC]
RewriteRule ^ %{REQUEST_SCHEME}://%{HTTP_HOST}/?title=%1 [L]

# The solution(the solution is required here):
# RewriteRule ^ /?title=%1 [L]

DirectoryIndex /m/index.htm /m/index.php /m/index.html
</ElseIf>

Important note: there is no relation between the full .htaccess file and the problem, the reason for this update is for the small chance I have made a mistake, anyway I have tested the .htaccess file with only the 3 lines from the question.

HERE IS THE HTTPD.CONF FILE

Last update:

RewriteEngine On    

# The actual condition is really long one so I replaced it for illustration.
RewriteCond %{HTTP_USER_AGENT} (iPhone|Blackberry|Android) [NC]

RewriteCond %{HTTP_HOST} !^m\.example\.com$ [NC]
RewriteRule .* http://m.example.com%{REQUEST_URI} [R,L]

RewriteCond %{REQUEST_URI} ^/([a-z-]+)/?$ [NC]
RewriteRule .* /?title=%1 [L]


<If "%{HTTP_HOST} = 'm.avielfadida.ml'">
    DirectoryIndex /m/index.htm /m/index.php /m/index.html
</If>

I have installed MySQL and i am trying to understand few things:

• The is several configuration *.ini files, Does the server automatically choose one of them or this files used as templates and i should create my.ini file with my own configuration.
• If i should create my own my.ini file so doe's the server automatically look for my.ini, Is there a way i can rename the .ini file as i want and configure MySQL to look for myAnother.ini

If anyone can help me here please i will be very thankful, Thank you all and have a nice day.

I am trying to understand some things about Rip V1 and V2 but I'm not sure if I'm right,

As I know Rip V1 doesn't "advertise" subnet masks, and doesn't support VLSM. If i understand right Even if Rip V1 for example supports VLSM it doesn't matter, Becouse the Rip V1 Only "advertise" the IP address, If some one can please confirm/expand/correct me I will be very thankful, Thank you all and have a nice day.
