No, never tried it yet.

You can transform the X-Ban headers into a ban expression with 
std.collect and regsuball:

| if (req.request == "BAN") { // && auth
|     std.collect(req.http.X-Ban); // Combine X-Ban headers, separated 
by ", "
|     std.log("banning URLs: " + req.http.X-Ban);
|     ban("obj.X-Purge-URL ~ (" + regsuball(req.http.X-Ban, ", ", "|") + 
")");
|     error 200 "Added to ban-list";
| }

A very large number of X-Ban headers in a single request could exceed 
workspace limits and require changes to runtime parameters 
(sess_workspace, http_max_hdr, http_req_hdr_len, http_req_size)

Indeed, it might be better to iterate over the headers in an Inline-C loop.
