modify Host header

["Eqbal Z" <eqbalz@xxxxxxxxx>]

I need to modify the Host header for my application in order to add the port information.

I tried the following directive

 

RequestHeader set Host "%{HOST_NAME}e:443"

 

This sets it to (null):443

 

How do I get the host name value here? For example if the request comes in as http://www.myhostname.com:8100/requested_resource

I am trying to get the www.myhostname.com part in the above directive by using %{HOST_NAME}e

 

Any help is greatly appreciated.

 

Thanks.
