There are additional Web Part options you can set in the SharePoint web.config file. The web.config file is a text file containing custom XML elements. You can edit this file using a text editor, such as Microsoft Notepad. By default, the Web.config file is located in the C:\Inetpub\wwwroot\ folder.

The following is a summary of these additional Web Part options and their values.

If your server is behind a proxy server or firewall, you must also edit the web.config file for each virtual server for which you want to enable the online Web Part library. In a server farm environment, you must edit this file for each virtual server in every front-end Web server in the server farm.

1. On your Web front-end server computer, open Notepad, navigate to the folder containing the virtual server for which you want to enable the online Web Part gallery, and then open the web.config file under the following directory:

   \Inetpub\wwwroot

2. In the web.config file, add the following lines.

   <system.net>
     <defaultProxy>
     <proxy proxyaddress="http://Proxy_Server:port" bypassonlocal = "true"/>
     </defaultProxy>
   </system.net>
   

   Where Proxy_Server:port is the proxy server or firewall used for your environment.

3. Save and close the web.config file.
4. Repeat steps 1 through 3 for each virtual server for which you want to enable access to the online Web Part gallery.

1. On a top-level Web site, click Site Settings.
2. Under Administration, click Go to Site Administration.
3. Under Site Collection Galleries, click Manage Web Part gallery.
4. On the Web Part Gallery page, click New Web Part.

You can remove a Web Part from the gallery if you want to make it unavailable to users. If a user has already used a Web Part in the site, and you delete the Web Part from the site gallery, the Web Part will remain on the Web Part Page and will still work. However, if an administrator on the server computer removes the Web Part assembly that contains the Web Part from the server, or marks the assembly as unsafe in the Web.config file for the server, the Web Part will no longer run and the user will see an error message.

1. On the Web Part Gallery page, next to the Web Part that you want to remove, click the Edit icon.
2. On the Web Part Gallery: Web Part Name page, click Delete.
3. Click OK to delete the Web Part.
