Throttle https virtual server requests, with non terminated ssl connections

Question

&nbsp;This is what I'd like to implement:  &nbsp;
&nbsp;---- https request ---- \              F5                  ----- https request --- \     Web server
&nbsp;---- client certificate - /    irule https Throttle   ---- client certificate -   / &nbsp;&nbsp;
&nbsp;I'm trying to use http throttle v10 and above: https://devcentral.f5.com/wiki/iRules.HTTP-Request-Throttle-version-10-1-and-above.ashx&nbsp;
&nbsp;Without ssl-termination, https virtual server doesn't work when applying an http profile.&nbsp;
&nbsp;This is the http-profile I'm using: &nbsp;&nbsp;
&nbsp;         ltm profile http /Partition1/profile_HTTP {
&nbsp;                  app-service none
&nbsp;                  defaults-from /Common/http
&nbsp;         }&nbsp;&nbsp;&nbsp;
&nbsp;Is it possible to throttle https request through irule https with non f5 ssl termination? &nbsp;
&nbsp;Is it possible to configure a http profile for a https virtual server? &nbsp;

Eszer, 
&nbsp;  
&nbsp; Your diagram shows client certificate on both sites, I assume you're going to have an SSL profile on the F5 and bridge SSL?  You have to, at a minimum, have a server SSL profile on the HTTPS VIP in order to use the HTTP_REQUEST event in your iRule.

&nbsp; SSL has to be terminated on the F5 for you to be able to use the HTTP events in an iRule.  You can, however, configure both a server and client side profile to keep the over-the-wire traffic encrypted. 
&nbsp; Is it possible to configure a http profile for a https virtual server?   
&nbsp; Yes

&nbsp;Thanks John, but we already tried  terminating ssl connections in f5 and re-encrypt traffic, performance rate is unacceptable. &nbsp;
&nbsp;Too slow in  f5 ltm 1600...

&nbsp; Eszer, 
&nbsp;  
&nbsp; Sorry to hear that.  If there is a security requirement to keep the traffic encrypted inside your network I'm afraid that I can't think of a way to do what you're looking for unless it is built into the application layer.  The F5 has to have the traffic decrypted in order for it to inspect layer 4+. 
&nbsp;  
&nbsp; Best of luck, 
&nbsp; John

thanks anyway, we'll have to make big changes on application layer

&nbsp;Can you provide more details on this? I've done this in multiple environments and haven't see any added latency or performance degradation. In reality, the ability to use a 2048-bit key on the client side while using a 1024-bit key on the server side should improve performance. Having the decryption done on commodity CPUs should never perform better.
