Rewrite an HTTP request

We are running v11.4.1 on our Bigip F5. I know how to rewrite url's with an irule however I'm not sure how to go about rewriting the following. A link (which cant be changed) on one of our websites points to "https://webserver.mycompany.com/cp/render.UserLayoutRootNode.uP?uP_tparam=utf&utf=%2fcp%2fip%2flogin%3fsys%3dsctssb%26url%3dhttp://webserver2.mycompany.com/devl/twbkwbis.P_GenMenu?name=bmenu.P_FinInfoMnu". We need the F5 to look for this HTTP request and when it sees "http://webserver2.mycompany.com", it should rewrite it to "https://webserver2.mycompany.com". Everything else around the HTTP request needs to stay untouched. Can I use a rewrite profile, irule, or some other method to get this done? How would I do this?

    Create new profile using the rewrite uri translation profile to get this completed. Set the rule type as request in your case.

    I'm not very good with this but based on what you wrote, this is what I did: 1. Profiles/Services/Rewrite 2. Click "Create New Profile". Entered a name, chose /Common/rewrite-uri-translation for the "Patent Profile" and set "Uri Translation" for the "Rewrite Mode" 3. Under "URI Translation/Settings/Request Settings", "Rewrite Headers" and "Insert X-Forwarded-For Header" are checked. 4. Under "URI Translation/Settings/Response Settings", "Rewrite Headers" and "Rewrite Content" are checked. 5. Under "URI Rules", I clicked "Add" and selected "Request" for "Rule Type". Then for the "Client URI", I pasted in "https://webserver.mycompany.com/cp/render.UserLayoutRootNode.uP?uP_tparam=utf&utf=%2fcp%2fip%2flogin%3fsys%3dsctssb%26url%3dhttp://webserver2.mycompany.com/devl/twbkwbis.P_GenMenu?name=bmenu.P_FinInfoMnu". 6. For "Server URI" I pasted in the same string but with the https instead of http.

     

    However, when I click OK to save it, I get the following error:

     

    MCP Error01070734:3: Configuration error: /Common/name_uri_rewrite: Client path '/cp/render.UserLayoutRootNode.uP?uP_tparam=utf&utf=%2fcp%2fip%2flogin%3fsys%3dsctssb%26url%3dhttp://webserver2.mycompany.com/devl/twbkwbis.P_GenMenu?name' must begin and end with '/'

     

    I probably have it misconfigured, but can't tell where the problem is. Any ideas?
