URLs -- no.

Domains -- yes, in most cases. Most SSL clients should send a TLS SNI
extension that contains some variation of the intended domain name. To
get access to SNI, you should tell your Squid to peek at the SSL client

  ssl_bump peek step1
  ssl_bump splice all

If you also want to know the site certificate details, then you would
need to peek at the server handshake as well:

  ssl_bump peek all
  ssl_bump splice all

N.B. Please note that I do not know what "webchain websites" means.
