# Spread for ASP.NET Redistribution

undefined

## Content



Please review this information concerning redistribution of Spread for ASP.NET with your application.

## Server Requirements

You must deploy to a Microsoft Internet Information server.

## Server Files

Place the assemblies that come with Spread for ASP.NET in either your server's global assembly cache (GAC) or in your application directory's \\bin folder under the **wwwroot** directory on your server.

Place the following assemblies on your server:

*   FarPoint.Web.Spread.dll
*   FarPoint.CalcEngine.dll
*   FarPoint.Excel.dll
*   FarPoint.PDF.dll
*   FarPoint.Web.Chart.dll (if you use the Chart control or Sparklines)
*   FarPoint.Web.Spread.Extender.dll (if you use the extender classes)
*   System.Web.Extensions.dll (if you use the FarPoint.Web.Spread.Extender.dll)
*   AjaxControlToolkit.dll (if you use the FarPoint.Web.Spread.Extender.dll)
*   FarPoint.Mvc.Web.Spread.dll (if you use Spread in an MVC3 project)

Place the **fp\_client folder** (installed originally in \\Program Files\\Common Files\\FarPoint Technologies) and its subfolders provided with Spread for ASP.NET under your server's **wwwroot** directory, or, if you wish to put it elsewhere, set up a virtual directory in IIS Manager to point to the location of that folder's contents.

The fp\_client folder can also be placed in the web application directory. The following code would need to be added to the web config file. For example:

```xml
<?xml version="1.0"?>
<configuration>
  <system.web>
    ...
  </system.web>
  <appSettings>
    <add key="fp\_client" value="fp\_client" />
  </appSettings>
</configuration>
```

Be aware that Spread for ASP.NET creates a Web server control that serves up HTML pages for clients and it also puts HTC files in a directory on the client machine for client-side scripting capability.

## Permission Requirements

If you use the Spread control on medium trust web sites, you need to add SerializationFormatter and Reflection permissions to the machine config file, web\_mediumtrust.config. The SecurityPermission needs the UnmanagedCode and SerializationFormatter flags. For example:

```xml
<IPermission class="SecurityPermission" version="1" Flags="Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration, UnmanagedCode, SerializationFormatter"/>

<IPermission class="ReflectionPermission" version="1" Unrestricted="true" Flags="ReflectionPermissionFlag.MemberAccess"/>
```
