RequestReduce

#RequestReduce RequestReduce Makes your website faster - sometimes much faster - with almost no effort

• Auto generates sprites from your background images
• Optimizes Sprite PNG format and compression
• Minifies CSS and Javascript
• Optimizes [caching headers and ETags] (http://github.com/mwrock/RequestReduce/wiki/Will-browsers-cache-the-css-and-image-files-that-RequestReduce-serves%3F)
• Runs on any IIS web site including Classic ASP and PHP
• Can sync content accross [multiple web servers] (http://github.com/mwrock/RequestReduce/wiki/Will-RequestReduce-sync-css-and-sprite-image-files-accross-all-of-the-web-servers-in-my-web-farm%3F)
• Works well with [CDNs] (http://github.com/mwrock/RequestReduce/wiki/Can-I-have-all-RequestReduce-CSS-and-sprite-resources-pulled-from-a-CDN%3F)
• Compiles [Less, Sass and Coffee script] (https://github.com/mwrock/RequestReduce/wiki/Less%2C-Sass-and-Coffee-Script-Compilation)

##Getting started

• If you have [Nuget] (http://docs.nuget.org/docs/start-here/installing-nuget), simply enter Install-Package RequestReduce in the Package Manager Console and skip steps two and three, otherwise download the latest RequestReduce version [here] (http://www.requestreduce.com/)
• Extract the contents of the downloaded zip and copy RequestReduce.dll and optipng.exe to your website's bin directory
• If you want to sync multiple servers with SqlServer copy te DLLs in RequestReduce.SqlServer to your bin directory
• If you have Less, Sass or Coffee scripts, copy the DLLs from RequestReduce.SassLessCoffee to your bin to compile these to CSS and Javascript
• Add the RequestReduceModule to your web.config or using the IIS GUI.

Assuming you are using IIS 7, you would add it by ensuring that your web.config's system.webServer/modules element contains an add element as follows:

<system.web>
  <httpModules>
    <add name="RequestReduce" type="RequestReduce.Module.RequestReduceModule, RequestReduce" />
  </httpModules>
</system.web>
<system.webServer>
  <validation validateIntegratedModeConfiguration="false"/>  
	<modules>
      <add name="RequestReduce" type="RequestReduce.Module.RequestReduceModule, RequestReduce" />
	</modules>
</system.webServer>

All background images you want to sprite [must have an explicit width in their css class] (http://github.com/mwrock/RequestReduce/wiki/Can-I-make-changes-to-my-CSS-classes-to-optimize-RequestReduce-spriting%3F). Otherwise RequestReduce cannot guarantee that the background positions it injects will not cause adjacent sprites to bleed into a background image's view port. Also, RequestReduce will ignore repeating images so make sure to mark the image no-repeat if it is not a repeating image.

##Troubleshooting If RequestReduce does not appear to be doing anything, check out this [troubleshooting wiki] (https://github.com/mwrock/RequestReduce/wiki/RequestReduce-is-not-working.-I-don%27t-see-any-spriting-or-minification.-How-can-I-troubleshoot-this%3F) which provides several scenarios, options and debugging tips for figuring out why your content may not be being reduced. Also check the [list of wiki support pages] (https://github.com/mwrock/RequestReduce/wiki) which provides documentation addressing several topics to help you optimize RequestReduce and explain how RequestReduce works.

##Requirements

• The Core RequestReduce Dll is Compatible with Framework versions 3.5 and 4.0
• Sql Server integration and Less, Sass and Coffee compilation require .net 4.0
• Standard Features are Medium Trust compliant
• The identity that your asp.net worker process runs under must have write access to your web root directory for creating sprite and css files

##What's Next? There are a ton of features I intend to add in order to make web performance optimizations just happen as part of installing Request Reduce. Here is what's at the top of the backlog:

• Support defered javascript loading
• Leverege CSS 3 to allow RequestReduce to sprite more images without any need for css modifications for supporting browsers
• Options to sprite foreground images
• Provide a command line utility for incorporating RequestReduce optimizations into a build task
