I want to change SSL bindings to a replacement certificate, but don't want to affect logged in users.

Will doing this cause the Application Pools for the web site to recycle?

Many thanks,

If I remove SSL binding completely and then re-add the same again, my app pool is still running without recycling. But the app pool I have tested runs PHP via FastCGI which may work completely different to the (hence the comment a not the answer). – LazyOne Jun 15 '11 at 11:48
Thanks for the comment, good to know. Still keen to find out if it'll affect Asp.Net apps. – Kenny Jun 15 '11 at 11:54
Well, you can try this (if you can, of course -- maybe this app is not designed to work on non-standard ports etc): 1) duplicate your site in question on another app pool (put it on the same SSL certificate but different port); 2) login as a customer there; 3) replace certificates and see if it the job (if I understand correctly you will be logged out on website if app pool recycles). If you need to perform this operation rather urgently it may be quicker compared for someone posting the 100%-assured answer here. – LazyOne Jun 15 '11 at 12:03

I have just done this in IIS7.5 and it did reset the application pool
