Webserver based media serving in Hybris

• Create an extension called staticmedia with a new class named ApacheMediaUrlStrategy that implements MediaURLStrategy interface. By default Hybris uses a base-64 encoded context request parameter that will not work properly in Apache. The ApacheMediaUrlStrategy uses a folder stategy so that apache can directly point to that directory. The below code in the class returns back //hostName/static/media/ in witch mediaHostUrl is an instance variable in ApacheMediaUrlStrategy class that contains hostName/static/media

return new StringBuilder(mediaHostUrl.length() + location.length() + 3).append("//").append(mediaHostUrl).append('/').append(location).toString();

• Add configuration properties to the local.properties to specify the mediaHostUrlwith an appropriate URL that points to you media serving apache layer and change the mediaurlstrategy

media.apachemedia.url= media.folder.images.url.strategy=apacheMediaURLStrategy

• Add the new strategy to the staticmedia-spring.xml file

<beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans.xsd">     <bean id="apacheMediaURLStrategy" class="com.package.staticmedia.media.url.impl.ApacheMediaUrlStrategy">         <property name="mediaHostUrl" value="#{configurationService.configuration.getProperty('media.apachemedia.url')}" />     </bean> </beans>

• Create ysynch to copy the image contents to the media.apachemedia.url
• Modify httpd.conf file to hanlde the media url inside the VirtualDirectory with 7 days of  cache expiry for images and 10 minutes for the _ui directory
