Can codebase work with a HTTP path, or are we doomed to "HTTP download of assemblies has been disabled for this appdomain"?

Question

Hello All,
After my long research I still can't load dll via <codeBase> .
I used in IIS 7.5.
I have client/server application.
Client is asp.net pure application that call to wcf service. 
Wcf Service have reference to SingleCalculation.dll. In wcf service web.config I define <runtime></runtime>
<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="SingleCalculation" publicKeyToken="82e196dda8eaccb5" />
        <bindingRedirect oldVersion="2.0.0.0-3.0.0.0" newVersion="2.0.0.2" />
        <codeBase version="2.0.0.2" href="http://192.168.126.100/SingleCalculation.dll" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
This is Error :
Could not load file or assembly 'SingleCalculation, Version=2.0.0.2, Culture=neutral, PublicKeyToken=82e196dda8eaccb5' or one of its dependencies. HTTP download of assemblies has been disabled for this appdomain. (Exception from HRESULT: 0x80131048)
Please help me understand what I need to do to load dll via HTTP.
I believe this is iis issue , because this dll I can load in next configuration:
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
     <dependentAssembly>
       <assemblyIdentity name="SingleCalculation"
publicKeyToken="82e196dda8eaccb5" />
       <bindingRedirect oldVersion="2.0.0.0-3.0.0.0"
newVersion="2.0.0.2" />C:\temp\TestFolder
       <codeBase version="2.0.0.2"  href="file:///c:/temp/TestFolder/SharedAssembly/SingleCalculation.dll"/>
      </dependentAssembly>
    </assemblyBinding> 
Thanks,
Best Regards

Hi,
About the issue, I suggest that you post it in IIS forum.
this issue indicates that AppDomainSetup.DisallowCodeDownload has been set
on this domain. Setting its flag will prevent any http:// download of assemblies., please refer to the similar discussion:
