Retain Orginal URL after Reverse Proxying

Question

I am trying to do a reverse proxy using Apache config file (Apache 2.2)
I am able to successfully 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? - if I am using a correct approach? any alternate options available? debugging options to find out where my config goes wrong ?
<Macro SingleNode %h1 %lp %rp>
<Location /%lp/>
Header add Set-Cookie "%Chat_SID=h.%{BALANCER_WORKER_ROUTE}e;\
path=/%lp/;" env=BALANCER_ROUTE_CHANGED
Header edit Location "^(.*pkma-usis.kaddi.sonet.fe.*/%lp/)(.*)$" "/%lp/$2"
</Location>
<Proxy balancer://%lpCluster>
BalancerMember http://%h1 min=1 smax=3 max=10 ttl=10 route=%h1
</Proxy>
ProxyPassReverse /%lp/ http://%h1/%rp/
RewriteRule ^/%lp/(.*) balancer://%lpCluster/%rp/$1 [proxy]
ProxySet balancer://%lpCluster stickysession=%Chat_SID
</Macro>

Hi,
I am not sure I 100% understand you setup but it is possible to retain the URL after a proxy :-)
Here is a edited example from one of our customers:
1. httpd.conf
<VirtualHost 172.30.123.10:80>
  ServerName theheat.dk
  RewriteEngine On
  RewriteCond %{HTTPS} off
  RewriteRule ^(.*)$ https://theheat.dk$1
</VirtualHost>2. ssl.conf
<VirtualHost 172.30.123.10:443>
ServerName theheat.dk
RewriteEngine On
RewriteRule ^/$ /example/faces/Home [R=301]
RequestHeader set WL-Proxy-SSL true
ProxyPass        /example/ http://wintermute:8001/example/
ProxyPassReverse /example/ http://wintermute:8001/example/3. Admin Console
In the Admin Console navigate to the Managed Server running on port 8001 and find Configuration => General => Advanced.
Put a check mark in "WebLogic Plug-In Enabled" even though your are not using the mod_wl plug-in.
Now select the Protocols tab and then HTTP. Set "Frontend Host" to theheat.dk and for "Frontend HTTPS Port" input 443.
Hope it helps.
