Set header key based on SSL ID

Is there a way to set a header key based on SSL ID value with HAProxy 1.5? We would like to use the SSL ID as the session ID for clients who do not support cookies.

First, to my knowledge, the answer is no.

However, there are other handy techniques to handle folks who do not support cookies. Provided that Javascript is supported, take a page out of Microsoft's book and try something that's actually pretty cool about ASP.NET apps.

Add a Javascript on_click handler to every link and an on_submit to forms. Then simply generate a post that contains the session ID, which is hidden in a hidden field or embedded in the Javascript. Works quite well and removes the requirement for cookies.

To be clear, I'm not suggesting that you use ASP.NET. I'm just suggesting that you use the technique. :)
