mod_rewrite problem

[ckevin]

I have just hardly setup the Apache 1.3.14 in RedHat 6.2 and wish to use mod_rewrite feature... What I wish to do is

anyuser.MY.com --> /home/MY/user/anyuser
Dir.anyuser.MY.com --> /home/MY/user/anyuser/Dir

And here is the lines needed in httpd.conf:

# Rewritelog logs/rewrite.log
# RewritelogLevel 9

RewriteMap lowercase int:tolower
RewriteEngine on

RewriteCond ${lowercase:%{HTTP_HOST}} !^$
RewriteCond ${lowercase:%{HTTP_HOST}} !^www\.MY\.com$

RewriteCond ${lowercase:%{HTTP_HOST}} ^www\.[^.]+\.MY\.com$
RewriteRule ^(.+) ${lowercase:%{HTTP_HOST}}$1 [C]
RewriteRule ^www\.([^.]+)\.MY\.com(.*) /user/$2$3 [L]

RewriteCond ${lowercase:%{HTTP_HOST}} ^www\.[^.]+\.[^.]+\.MY\.com$
RewriteRule ^(.+) ${lowercase:%{HTTP_HOST}}$1 [C]
RewriteRule ^www\.([^.]+)\.([^.]+)\.MY\.com(.*) /user/$3/$2$4 [L]

However, I run "apachectl configtest" and it said ok but I can't get what I need...

I have setup WildCard (*.MY.com) in DNS and *.MY.com alias with MY.com in Apache, when I type:
http://kevin.MY.com

It only displays the main page of MY.com but not /home/MY/user/kevin!

Please help! I have tried many times but failed...

I don't know if this helps but try it anyway:

RewriteEngine on
RewriteMap lc int:tolower
RewriteCond %{HTTP_HOST} ^$ [NC]
RewriteRule ^(.*) - [L]
RewriteCond %{HTTP_HOST} ^www\.MY\.com$ [NC]
RewriteRule ^(.+) - [L]
RewriteCond %{HTTP_HOST} ^www\.[^.]+\.MY\.com$ [NC]
RewriteRule ^(.+) %{HTTP_HOST}=$1 [C]
RewriteRule ^(.*)=(.*) ${lc:$1}$2 [C]
RewriteRule ^www\.([^.]+)\.MY\.com(.*) /home/MY/user/$1$2 [L]
RewriteCond %{HTTP_HOST} ^www\.[^.]+\.[^.]+\.MY\.com$
RewriteRule ^www\.([^.]+)\.([^.]+)\.MY\.com(.*) /home/MY/user/${lc:$2}/$1$3 [L]

Note: I didn't lc it initially just to conserve resources since I don't think you even need to do that at the beginning.

>>RewriteCond ${lowercase:%{HTTP_HOST}} !^www\.MY\.com$

This line is redundant since http://www.MY.com has uppercase already.

>>I run "apachectl configtest" and it said ok but I can't get what I need.

Because your $3/$2$4 was wrong. There isn't any $4.

If I understood your situation correctly, your domain is always in uppercase while username alias from URL part is case-insensitive but the username in the file system part MUST be lowercase.

thank you freebsd,

sorry, but the result is still the same...

when kevin.MY.com, it still go to the main page of MY.com......

Actually, the MY.com is using the Name-based hosting, so if not alias *.MY.com with MY.com in Apache, the kevin.MY.com would go to the general page of that name-bsaed IP only.

Thanks,

kevin

I'm a bit confused now, why don't you post the NameVirtualHost line and the
<VirtualHost> block here so we can take a look at it.

[ckevin]

sorry for the confuse...

What I have done for:

(1) in DNS, wildcard on, both *.imazn.com and imazn.com have a A record to the same IP 1.1.1.1

(2) In httpd.conf:

NameVirtualHost 1.1.1.1

and my record for imazn.com:

<VirtualHost 1.1.1.1>
DocumentRoot /home/imazn/www
ServerName www.imazn.com (http://www.imazn.com)
ServerAdmin webmaster@imazn.com
ServerAlias imazn.com

RewriteMap lowercase int:tolower
RewriteEngine on

RewriteCond ${lowercase:%{HTTP_HOST}} !^$
RewriteCond ${lowercase:%{HTTP_HOST}} !^www\.imazn\.com$

RewriteCond ${lowercase:%{HTTP_HOST}} ^www\.[^.]+\.imazn\.com$
RewriteRule ^(.+) ${lowercase:%{HTTP_HOST}}$1 [C]
RewriteRule ^www\.([^.]+)\.imazn\.com(.*) /user/$2$3 [L]

RewriteCond ${lowercase:%{HTTP_HOST}} ^www\.[^.]+\.[^.]+\.imazn\.com$
RewriteRule ^(.+) ${lowercase:%{HTTP_HOST}}$1 [C]
RewriteRule ^www\.([^.]+)\.([^.]+)\.imazn\.com(.*) /user/$3/$2$4 [L]

</VirtualHost>

Do you think it is ok? I tried putting the mod_rewrite outside the <VirtualHost> tag but the result seems the same...

Thanks,

kevin

>>Do you think it is ok?

Not quite.

Your Rewrite stuffs should go first (above your VirtualHost block)

Your VirtualHost block should look something like so:
<VirtualHost 1.1.1.1>
RewriteEngine on
RewriteOptions inherit
DocumentRoot /home/imazn/www
ServerName www.imazn.com (http://www.imazn.com)
ServerAdmin webmaster@imazn.com
ServerAlias imazn.com
</VirtualHost>

[ckevin]

freebsd,

thank you very much for your advice... I have checked for my and your mod_write scripts but still, both fail, it (kevin.imazn.com) does not display the page at "/home/imazn/user/kevin".

still have any idea? i don't want to give up...

really thanks, http://www.linuxnewbie.org/ubb/smile.gif

>>i don't want to give up

Then fix the problem with your rules first, it won't work with the following in the first place:

RewriteRule ^www\.([^.]+)\.imazn\.com(.*) /user/$2$3 [L]

and

RewriteRule ^www\.([^.]+)\.([^.]+)\.imazn\.com(.*) /user/$3/$2$4 [L]

Also, if you don't want to start out with my codes, that is your choice. I don't think you understand the difference comparing yours and mine anyway.

My final suggestion, you should not use false condition all the time:

RewriteCond ${lowercase:%{HTTP_HOST}} !^$

In addition, don't use lowercase for your first condition, it's redundant, you are checking whether or not HTTP_HOST is blank, definitely useless to check for the case.

Why don't you enable the RewriteLog line (for debugging purpose only) and see what happen.

Good Luck!

[ckevin]

I have put your mod_rewrite scripts and enable the log:

In httpd.conf:

<VirtualHost 1.1.1.1>
Rewritelog logs/rewrite.log
RewritelogLevel 9
RewriteEngine on
RewriteMap lc int:tolower
RewriteCond %{HTTP_HOST} ^$ [NC]
RewriteRule ^(.*) - [L]
RewriteCond %{HTTP_HOST} ^www\.imazn\.com$ [NC]
RewriteRule ^(.+) - [L]
RewriteCond %{HTTP_HOST} ^www\.[^.]+\.imazn\.com$ [NC]
RewriteRule ^(.+) %{HTTP_HOST}=$1 [C]
RewriteRule ^(.*)=(.*) ${lc:$1}$2 [C]
RewriteRule ^www\.([^.]+)\.imazn\.com(.*) /home/imazn/www/user/$1$2 [L]
RewriteCond %{HTTP_HOST} ^www\.[^.]+\.[^.]+\.imazn\.com$
RewriteRule ^www\.([^.]+)\.([^.]+)\.imazn\.com(.*) /home/imazn/www/user/${lc:$2}/$1$3 [L]
DocumentRoot /home/imazn/www
ServerName www.imazn.com (http://www.imazn.com)
ServerAdmin webmaster@imazn.com
ServerAlias imazn.com
</VirtualHost>

I hope you can help me to figure the problem... thanks a lot.

What URL did you try? It doesn't seem to get to the 3rd condition at all. Still, the problem could be something else instead of mod_rewrite at all.

[ckevin]

I set the testing URL
http://freshwoman.imazn.com

do you think I need to set:

ServerAlias imazn.com *.imazn.com or just

ServerAlias imazn.com is ok?

The only difference is if set the wild card on, the *.imazn.com would display the main page of imazn.com....

Thanks,

kevin

[freebsd]

Try to remove ServerAlias line completely.

[ckevin]

I have removed the Alias but it still can't work...

Thanks,

kevin
