How to replace missed files using mod_rewrite.
Here my mod_rewrite rule to check and replace missed image with NotAv.jpg icon.
#Start rewrite Engine
RewriteEngine on
#if /var/www/ “Requested file name” is not equal to (f)inded
RewriteCond /var/www%{REQUEST_FILENAME} !-f
#then rewrite all file in /public not finded with NotAv.jpg image
RewriteRule ^/public/.*$ /public/images/NotAv.jpg [PT]
#Log directives.
RewriteLog rewrite.log
RewriteLogLevel 1
Here a example of base configuration for Apache Http and WebDav:
1) First of All you have to create a .htaccess file:
[ApacheRoot]/bin/htpasswd -c /usr/local/apache2/.htpasswd username
2) Create an include in your httpd.con (I prefer to create a folder and include all *.conf file) :
Include conf/include/*.conf
3) create a dav.conf file and put it in the include dir.
#### dav.conf
#Loading Mudels
LoadModule dav_module modules/mod_dav.so
LoadModule dav_fs_module modules/mod_dav_fs.so
#Dav lck and timeout
DavLockDB /var/lock/dav/DavLock
DAVMinTimeout 600
#WebDav Virtual host enabled
<VirtualHost *:80>
ServerName dav.your.domain
Alias /dav /var/www/dav
<Location /dav>
AuthType Basic
DAV On
AuthName “WebDAV”
AuthUserFile “/usr/local/apache2/.htpasswd”
Options None
Require user username
</Location>
<Location />
Order Allow,Deny
Allow from all
</Location>
</VirtualHost>
4) Restart your Apache.
5) Now you should connect with a WebDav Client.
