title: modsecurity "Inbound Anomaly Score"
body: <p>I got a lot of this error on my logs in a site hosting by OVH shared PRO =&gt;</p>
  <pre><code>ModSecurity: Warning. 
  Operator LT matched 20 at TX:inbound_anomaly_score.
  [file &quot;/usr/local/apache2/conf/modsecurity/base_rules/modsecurity_crs_60_correlation.conf&quot;] 
  [line &quot;32&quot;] 
  [msg &quot;Inbound Anomaly Score (Total Inbound Score: 2, SQLi=, XSS=): Pragma Header requires Cache-Control Header for HTTP/1.1 requests.&quot;]
  </code></pre>
  <p>It seems it comes from the WAF's conf.
  Does anybody know how to workaround or fix those errors?</p>
