Retain Orginal URL after Reverse Proxying

[Bala <balamurugan.murthy@xxxxxxxxx>]

I am trying to do a reverse proxy using Apache config file.

I am able to succesfully reverse proxy a user from https://www4.dev.sonet.se/chatview/ to http://pkma-usis.kaddi.sonet.fe/chatview

But when i try to retain the host domain name after reverse proxy using "Header edit Location" directive, it fails.

i.e, After redirection to http://pkma-usis.kaddi.sonet.fe:80/chatview the user must see the URL as https://www4.dev.sonet.se/chatview. 

I wanted to know if what I am trying to do is feasible in the first place and if this is a good practice. Following is my config file. Can anyone please help 

me in this?
