Leverage browser caching how on apache or htaccess

Question

What to do here  I have a huge list of files that Google Speed Page said to  Leverage Browser Caching    but I don t know how  Do I mess or change the Apache config file  below  or do I put something in my  htaccess page     lt IfModule mod proxy c gt          ProxyRequests Off         CacheRoot   var run proxy          CacheSize 1024         CacheGcInterval 24      CacheMaxExpire 24      CacheLastModifiedFactor 0 1      CacheDefaultExpire 1      NoCache a domain com another domain edu joes garage sale com          lt Directory  disabled proxy  gt              Allow from example com             Deny from all             Order Deny Allow          lt  Directory gt       lt  IfModule gt                  mod expires is configured so that all static files but images          expire after 60 seconds  Any response that has a life span of more          than 5 seconds  see webperfcache conf  will be cached by webperfcache           Make sure your CGIs return a  Cache-Control  no-cache  header if you          elect to make your dynamically generated HTML pages not cache-able           If all your HTML pages are static you may also increase ExpiresDefault        lt IfModule mod expires c gt          ExpiresActive On         ExpiresDefault A60         ExpiresByType image bmp A3600         ExpiresByType image gif A3600         ExpiresByType image ief A3600         ExpiresByType image jpeg A3600         ExpiresByType image png A3600         ExpiresByType image tiff A3600         ExpiresByType image x-cmu-raster A3600         ExpiresByType image x-portable-anymap A3600         ExpiresByType image x-portable-bitmap A3600         ExpiresByType image x-portable-graymap A3600         ExpiresByType image x-portable-pixmap A3600         ExpiresByType image x-rgb  A3600         ExpiresByType image x-xbitmap A3600         ExpiresByType image x-xpixmap A3600         ExpiresByType image x-xwindowdump A3600         ExpiresByType audio basic A3600         ExpiresByType audio midi A3600         ExpiresByType audio mpeg A3600         ExpiresByType audio x-aiff A3600         ExpiresByType audio x-pn-realaudio A3600         ExpiresByType audio x-pn-realaudio-plugin A3600         ExpiresByType audio x-realaudio A3600         ExpiresByType audio x-wav A3600         ExpiresByType video mpeg A3600         ExpiresByType video quicktime A3600         ExpiresByType video x-msvideo A3600         ExpiresByType video x-sgi-movie A3600      lt  IfModule gt

I was doing the same thing a couple days ago. Added this to my .htaccess file:

ExpiresActive On
ExpiresByType image/gif A2592000
ExpiresByType image/jpeg A2592000
ExpiresByType image/jpg A2592000
ExpiresByType image/png A2592000
ExpiresByType image/x-icon A2592000
ExpiresByType text/css A86400
ExpiresByType text/javascript A86400
ExpiresByType application/x-shockwave-flash A2592000
#
<FilesMatch "\.(gif¦jpe?g¦png¦ico¦css¦js¦swf)$">
Header set Cache-Control "public"
</FilesMatch>

And now when I run google speed page, leverage browwer caching is no longer a high priority.

Hope this helps.

First we need to check if we have enabled mod headers c and mod expires c   sudo apache2 -l   If we don t have it  we need to enable them  sudo a2enmod headers   Then we need to restart apache  sudo apache2 restart   At last  add the rules on  htaccess  seen on other answers   for example  ExpiresActive On ExpiresByType image gif A2592000 ExpiresByType image jpeg A2592000 ExpiresByType image jpg A2592000 ExpiresByType image png A2592000 ExpiresByType image x-icon A2592000 ExpiresByType text css A86400 ExpiresByType text javascript A86400 ExpiresByType application x-shockwave-flash A2592000    lt FilesMatch     gif jpe g png ico css js swf    gt  Header set Cache-Control  public   lt  FilesMatch gt

This is what I use to control headers caching  I m not an Apache pro  so let me know if there is room for improvement  but I know that this has been working well on all of my sites for some time now   Mod expires  http   httpd apache org docs 2 2 mod mod expires html  This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses  The expiration date can set to be relative to either the time the source file was last modified  or to the time of the client access   These HTTP headers are an instruction to the client about the document s validity and persistence  If cached  the document may be fetched from the cache rather than from the source until this time has passed  After that  the cache copy is considered  expired  and invalid  and a new copy must be obtained from the source     BEGIN Expires  lt ifModule mod expires c gt  ExpiresActive On ExpiresDefault  access plus 1 seconds  ExpiresByType text html  access plus 1 seconds  ExpiresByType image gif  access plus 2592000 seconds  ExpiresByType image jpeg  access plus 2592000 seconds  ExpiresByType image png  access plus 2592000 seconds  ExpiresByType text css  access plus 604800 seconds  ExpiresByType text javascript  access plus 216000 seconds  ExpiresByType application x-javascript  access plus 216000 seconds   lt  ifModule gt    END Expires   Mod headers  http   httpd apache org docs 2 2 mod mod headers html  This module provides directives to control and modify HTTP request and response headers  Headers can be merged  replaced or removed     BEGIN Caching  lt ifModule mod headers c gt   lt filesMatch     ico pdf flv jpg jpeg png gif swf    gt  Header set Cache-Control  max-age 2592000  public   lt  filesMatch gt   lt filesMatch     css    gt  Header set Cache-Control  max-age 604800  public   lt  filesMatch gt   lt filesMatch     js    gt  Header set Cache-Control  max-age 216000  private   lt  filesMatch gt   lt filesMatch     xml txt    gt  Header set Cache-Control  max-age 216000  public  must-revalidate   lt  filesMatch gt   lt filesMatch     html htm php    gt  Header set Cache-Control  max-age 1  private  must-revalidate   lt  filesMatch gt   lt  ifModule gt    END Caching
