How to Update Doconut Version 1.0.5.2 or below

.NET Framework 4.7 .NET Standard / Core .NET 6 or higher

.NET Framework 4.7

The viewer requires HttpHandler to be registered via web.config file. Depending on your IIS version it can be done using the following section defined in web.config (also shown in our sample Asp.Net project’s web.config file)

Below IIS 7

<httpHandlers>

                                  <add verb="GET,POST" path="DocImage.axd" type="Doconut.DocImageHandler, Doconut" />

                                </httpHandlers>

For Webfarm, use this configuration

<httpHandlers>

                                  <add verb="GET,POST" path="DocImage.axd" type="Doconut.DiskImageHandler, Doconut" />

                                </httpHandlers>

IIS 7 and above

<httpHandlers>

                                  <add name="DocImage" verb="GET,POST" path="DocImage.axd" type="Doconut.DocImageHandler, Doconut" />

                                </httpHandlers>

For Webfarm, use this configuration

<httpHandlers>

                                  <add name="DocImage" verb="GET,POST" path="DocImage.axd" type="Doconut.DiskImageHandler, Doconut" />

                                </httpHandlers>
