Syncs static files to a content delivery network (CDN) such as Amazon S3 / CloudFront,MaxCDN and CloudFiles. To be used with WP-Supercache.
 
== Description ==

Front end optimisation plugin to be used with WP-Supercache.

Uploads/syncs your static files to a Content Delivery Network (CDN) with push CDNs such as Amazon S3 / CloudFront and CloudFiles as well as Origin Pull CDNs such as MaxCDN / NetDNA. You can choose files from your media library, theme directory, WordPress's wp-include directory and plugin directories as well as new media library uploads.

Plugin runs images thought smushit.com to losslessy compress images, as well as GD compression of images.

There is also concatenation of all Javascript and CSS files in the header and footer to one file each to reduce HTTP requests. Also moves the javascript file to the footer so the browser doesn't hold up the page load doing it. Leverages Google's Closure Compiler to remove whitespace, do simple and advanced optimisations to reduce file size.

This plugin requires WP Super Cache to be installed. As it will handle the rewriting of the inclusion of static files to ensure all static files will load from your CDN.

== Frequently Asked Questions ==

= Why should I care about fast loading web page? =

Because a speed affects your SEO and your sales. People aren't patient creatures, they want stuff as fast as possible. Google has stated that a page loading time makes up part of their page rank. Amazon found that for every 100ms in page loading caused them 1% in sales. Google found when they increased size of results from 10 results to 30 results and increased their page load by 0.5 seconds their traffic dropped by 20%. 

= Why does uploading files take so long with this installed? =

The reason for the increased time when uploading files is caused by using smushit which can take a 1+ seconds per image, GD compression and uploading to your CDN also increase the time spent handling the file. Since uploading new media happens only once per image the increase in time cause in the admin backend is saved on the front end page load.  

= Do you pre compress css and Javascript files before uploading to S3? =

Yes, the plugin gzips javascript and css files and adds a gzip content-type header to the files before uploading to S3 as S3 doesn't add these values to plain text files by default.

= Why do you upload static plugin files? =

Because some plugins also have images and static files that need to be displayed on your site, we also want the plugin to work even if you decide not to use the concatenation functionality of the plugin.

= Why do you concatenation Javascript and CSS files when there are others plugins that do it? =

The problem with these other plugins is that they don't upload the files to a CDN once they've been created.

= Do you upload concatenated Javascript and CSS files every time? =

No the files are uploaded to the Content Delivery Network (CDN) only once and they are then cached. If the CSS/Javascript files content changes then there will be a new file created and uploaded to the CDN. Using a different filename to avoid CDN edge caching conflicts.

= Why do I need to have WP Super Cache installed? =

You need to have this installed as we use their url changer functionality and they will help improve your site's speed.

= Why is there a custom directory sync? Doesn't the plugin sync everything I need by default? =

Well various plugins store images and static files in different places than the place we look by default, due to the large amount of places static files could be stored it would be near impossible for the plugin to automatically detect and sync the files.

= What sort of speed improvements can I expect? =

The page load improvements of a Content Delivery Network (CDN) can vary however it has been seen that by implementing use of a CDN can improve the speed of the site's loading by more than 75%.

= Is there anything special I need to do to have my new uploads sync to my Amazon S3? =

No with the plugin enabled and the Content Delivery Network (CDN) assigned as Amazon S3 /Cloudfront the uploads will happen automatically as well as other optimisations such compression.
