View State Caching and Java Script Minification

Following are the two steps that you need to follow in order to use content optimization feature of NCache:

Step 1: Update/Configure app browser file:

Create an App browser file in your asp.net application. It will be created under the directory of App_browsers.
Plug page adapters in the app browser file as following:

<browser refID ="Default">

<controlAdapters>

<adapter controlType = "System.Web.UI.Page" adapterType = "Alachisoft.NCache.Adapters.PageAdapter"/>

</controlAdapters>

</browser>

Here page adapter is plugged at page level. You can also plug it at any control level for which you want to cache the view state.

Step 2: Update/Configure web.config file:

You need to add the following assembly reference in compilation section of web.config file.

<compilation defaultLanguage = "c#" debug = "true">

<assemblies>

<add assembly = "Alachisoft.NCache.Adapters, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cff5926ed6a53769"/>

</assemblies>

</compilation>
You need to register a web config section which contains the settings/properties in web.config file.

<configSections>

<sectionGroup name = "ncContentOptimization">

<section name = "settings" type = "Alachisoft.NCache.ContentOptimization.Configurations.ContentSettings" allowLocation = "true" allowDefinition = "Everywhere"/>

</sectionGroup>

</configSections>
Add the actual setting/configuration section as follows:

<ncContentOptimization>

<settings enableMinification = "true" enableViewstateCaching = "true"

groupedViewStateWithSessions = "true"viewstateThreshold = "0" enableTrace = "true">

<cacheSettings cacheName = "mycache">

<expiration type="Sliding" duration = "300"/>

</cacheSettings>

</settings>

</ncContentOptimization>
enableMinification: Enable/disable the Java script minification.
enableViewstateCaching: Enable/disable the ViewState caching.
gropuedViewStateWithSessions: Enable/disable grouped view state with sessions. By default this attribute is false.
viewstateThreshold: Sets minimum threshold size of view state in bytes. ViewStates which are smaller than threshold value will not be cached.
enableTrace: Enable/disable logging.
cacheName: Name of the cache.
expiration type: Sets the expiration type which can either be Sliding, Absolute or None.
duration: Sets expiration interval in minutes.

Through querystring parameter "rpo=off", user can quickly turn off CSS and JS minification without modifying web.config. This facility is provided to the users to analyze the page load time with and without content optimization.
