How Do I Change The 'Document Mode' Of Ie In Web Config for IIS 6

Question

Hi,

In order to change the Document mode of IE in web config for my web application which is in IIS6.I have checked the below option which is adding the code using meta tag

<meta http-equiv="x-ua-compatible" content="edge">

It doesn't overrides my local compatibility settings.

i have checeked other options like adding code below <system.webserver>.But it will be working only for IIS7.

<configuration>
  <system.webserver>
    <httpprotocol>
      <customheaders>
        <clear />
        <add name="X-UA-Compatible" value="edge" />
      </customheaders>
    </httpprotocol>
  </system.webserver>
</configuration>

Can you please provide me the solution(Code) to change the Document mode(override the local compatibility settings) for IIS6

Thanks,

Hi @Tharani Santhanam,

Adding code <add name="X-UA-Compatible" value="edge" /> in web.config, this method of setting "Custom HTTP Headers" only works for IIS7 and higher versions. IIS6 cannot read this configuration element.

"IIS 6.0 replaces MetaBase.bin with two XML files named MetaBase.xml and MBSchema.xml. These files are stored on your computer in the systemroot\System32\Inetsrv folder. Only users who are members of the Administrators group can view and modify these files. The metabase configuration file, MetaBase.xml, stores most of the IIS configuration. Some IIS configuration values are also stored in the Windows registry. If a configuration value is one that you might need to configure or change, or if you can access the setting in the IIS 6.0 user interface, then the setting is typically stored in the IIS metabase."

Please try manually editing the setting "Custom HTTP Headers" using IIS6 Manager:

Open IIS Manager, right click on the website select Properties, select the tab HTTP Headers, and add the custom header "X-UA-Compatible: edge".

In addition, the product version you are using has ended its life cycle and is no longer supported; it is recommended that you use a newer version of the product for better security and stability and support services provided by Microsoft.
