Leverage browser caching y would this show as an error after speed tes

Okay so i'm running a speed test on my home page and get a error /warning in red -- Leverage browser caching

how can i solve this error any help

Not an error. It's a suggestion. A strong one. There are normally 3 color categories in these speed tests, red being the ones that would best help the speed of the site. I would like to know what you're using for testing so i can see exactly what it says. Error i am sure is not the proper term.

That is how. This does not help as much with dolphin sites or any other database driven website. Static content is best for this suggestion.

This suggestion also requires that the server is running apache with mod_expries extension installed.

Most modern browsers cache content on their own anyway.

you are absolutely  right it does not say error but for some reason i associated the red with error 

I'm using firefox speed tool 

I read an article  on boonex about caching and in this article they make claim that by installing and turning on the cache engine your site should speed up 4-10 folds yet after having the memcache engine install we are still getting the same speed result we have upgraded to a dedicated server to increase processing and ram  install cache engine and still have almost the same  speed rate which is affecting our bounce rate  

Try this it worked for me. After so many work i am able to make my score 90 for my website and everything is green but Combine images into CSS sprites is still red. i will do something for it.

Add this in your root .htaccess.

<IfModule mod_expires.c>
    # enable expirations
    ExpiresActive On
    # expire images/css/js/swf files after a month in the client's cache
    ExpiresByType application/x-shockwave-flash "access plus 30 days"
    ExpiresByType text/css "access plus 30 days"                
    ExpiresByType text/javascript "access plus 30 days"         
    ExpiresByType application/javascript "access plus 30 days"  
    ExpiresByType application/x-javascript "access plus 30 days"
    ExpiresByType application/x-gzip "access plus 30 days"                                       
    ExpiresByType image/gif "access plus 30 days"
    ExpiresByType image/jpeg "access plus 30 days"
    ExpiresByType image/png "access plus 30 days"
    ExpiresByType image/x-icon "access plus 30 days"
    ExpiresByType image/vnd.microsoft.icon "access plus 30 days" 
</IfModule>

@Prashank25 •          Thanks for the advice I will try this and keep you post 

Thanks i Tried the code and was able to get it up from 35 to 65 and was able to clear leverage browser caching 

 to Prashank25  small error the apostrophe in clients      expire images/css/js/swf files after a month in the client's cache

thanks for that, easy fix, bumped the score, most of what is left is stuff I don't want to cange. Reapet page loads are down to 1.6 seconds - to me it looks almost instantaneous. ;)
