Because of hack attempts apparently resulting from the previous posts, I've put IP Deny in place, and before doing that took another look at how it might affect security.
The default FrontPage "order deny,allow" lines allow anyone to GET or POST, and no one to PUT or DELETE. The changes that DenyIP made don't change that, but it has to change how
it's done so it can apply the denial lines globally.
It still wouldn't hurt to examine .htaccess after applying IPDeny, to review what it did and to make sure it's what you wanted.
A concise reference on how to interpret the Order, Allow, and Deny directives is at http://httpd.apache.org/docs/1.3/mod/mod_access.html
. I didn't find any documentation about rules of precedence (what if two or more rules conflict?). [Edit: I found one source, not definitive enough to post link, that said if access rules conflict, the rule farther down in the .htaccess file overrides the earlier one.]
