Note: that no patch is available for Apache 2.0.64.01.
1) Use SetEnvIf or mod_rewrite to detect a large number of ranges and then either ignore the Range: header or reject the request.
2) Limit the size of the request field to a few hundred bytes.
3) Use mod_headers to completely disallow the use of Range headers.
