URL Redirect with variable

Hi Again

We tried this irule and it looks redirect correctly but we have another issue like below

We will replace linux based reverse proxy to F5 and we don't want to see redirection url on browser, It will be show source url on browser but bring the target url ( Linux based reverse proxy works like this )

I think we need to write rewrite rule but i don't know how can i write this rule

Please could you help me for this situation

For more details you can see below,

Linux based reverse proxy config example

RewriteRule ^/sap/bc/srt/rfc/sap/TST_TEST_KONTROL(.*) http://tstrestr.abc.com:8011/sap/bc/srt/rfc/sap/TEST_KONTROL$1 [P,L]

RewriteRule ^/sap/bc/srt/rfc/sap/TST_TEST_CHANGE(.*) http://tstrestr.abc.com:8011/sap/bc/srt/rfc/sap/TEST_CHANGE$1 [P,L]

In this rule

^ = http://test.abc.com

(.*) = whatever comes put after $1

(?sap-client=010&sap-user=wsuser&sap-password=sm3abcde1fg)

It will going below site but can't change url link on browser http://tstrestr.abc.com:8011/sap/bc/srt/rfc/sap/TEST_KONTROL?sap-client=010&sap-user=wsuser&sap-password=sm3abcde1fg
