htaccess désactiver le cache pour des URL spécifiques

Question

J'utilise .htaccess pour mettre en cache mes images, les fichiers JS et CSS sur le front-end de mon site Web. Le site est construit sous Codeigniter 2.

Voici mon code:

RewriteEngine on 

#RewriteRule ^index\.php/[R=301] 

RewriteCond %{THE_REQUEST} index\.php 
RewriteRule ^index.php(?:/(.*))?$ https://www.mywebsite.com/$1 [R=301,L] 


RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond $1 !^(index\.php|resources|robots\.txt) 
RewriteRule ^(.*)$ index.php/$1 [L,QSA] 

#Compression Gzip 
<IfModule mod_deflate.c> 
AddOutputFilterByType DEFLATE application/x-javascript application/javascript 
text/javascript text/css text/html text/xml 
</IfModule> 

# Cache One month for most static assets 
<filesMatch ".(jpg|jpeg|png|gif|ico)$"> 
Header set Cache-Control "max-age=2628000, public" 
</filesMatch> 

#Force la redirection vers www. 
#RewriteCond %{HTTP_HOST} !^www\.mywebsite\.com$ [NC] 
#RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$ 
#RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$ 
#RewriteRule .? https://www.mywebsite.com%{REQUEST_URI} [R=301,L] 

RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://www.mywebsite.com/$1 [R,L]

<IfModule mod_headers.c> 
    <filesmatch "\.(ico|flv|jpg|jpeg|png|gif|css|swf)$">

    <filesmatch "\.(html|htm)$"> 
    Header set Cache-Control "max-age=7200, private, must-revalidate" 
    </filesmatch> 
    <filesmatch "\.(pdf)$"> 
    Header set Cache-Control "max-age=86400, public" 
    </filesmatch> 
    <filesmatch "\.(js)$">

    </filesmatch> 
</IfModule> 

Il fonctionne très bien. Cependant, quand je travaille dans le backend (www.mywebsite/admin), le cache s'applique également, ce qui est assez anoying lors de la mise à jour des images et des textes.

J'ai essayé cette solution au fond de mon fichier htaccess:
htaccess Disable cache if URL contains string?
mais mon contenu est lu encore de la mémoire cache.

J'ai essayé aussi le « Location » et directive « LocationMatch », mais il crée une erreur de serveur interne:

<Location /admin> 
FileETag None 
Header unset ETag 
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate" 
Header set Pragma "no-cache" 
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT" 
</Location > 

Y at-il quelqu'un qui pourrait aider à ce sujet s'il vous plaît? Merci!

Answer 1

<Directory /some/real/path/to/tmp> 
    Header Set Pragma "no-cache" 
    Header Set Expires "Thu, 1 Jan 1970 00:00:00 GMT" 
    Header Set Cache-Control "max-age=0, no-store, no-cache, must-revalidate" 
    Header Unset ETag 
    FileETag None 
</Directory> 

Cela devrait fonctionner.
