How to Allow Underscore in HTTP Header?

Hello All,   I am working on the requirement to allow underscores in HTTP headers by default F5 does not allow it. Can anybody let me know what I need to do at the F5 end to allow underscores like...

All you need to do to make this load balance properly is to apply a cookie persistence profile to your virtual server. In the virtual server you can configure it to insert X-Forwarded-For header as the URL requires. You do not need any special headers to achieve what that document describes.

Thanks all for your support.

 

Issue has been resolved. Underscores are allowed by default in F5, no specific configuration is required to achieve to allow underscores.

 

Thanks!!
