Block Microsoft Exchange Autodiscover requests
In some cases, Microsoft Exchange Autodiscover service requests can be “noisy,” triggering large numbers of HTTP 404
(Page not found) errors.
This example uses the matches
comparison operator and a regular expression to block autodiscover.xml
and autodiscover.src
requests:
Expression | Action |
---|---|
http.request.uri.path matches "/autodiscover.(xml|src)$" | Block |
