     1122      <p id="rfc.section.5.p.1">When more than one conditional request header field is present in a request, the order in which the fields are evaluated becomes
     1123         important. In practice, the fields defined in this document are consistently implemented in a single, logical order, due to
     1124         the fact that entity tags are presumed to be more accurate than date validators. For example, the only reason to send both <a href="#header.if-modified-since" class="smpl">If-Modified-Since</a> and <a href="#header.if-none-match" class="smpl">If-None-Match</a> in the same GET request is to support intermediary caches that might not have implemented <a href="#header.if-none-match" class="smpl">If-None-Match</a>, so it makes sense to ignore the <a href="#header.if-modified-since" class="smpl">If-Modified-Since</a> when entity tags are understood and available for the selected representation.
     1125      </p>
     1126      <p id="rfc.section.5.p.2">The general rule of conditional precedence is that exact match conditions are evaluated before cache-validating conditions
     1127         and, within that order, last-modified conditions are only evaluated if the corresponding entity tag condition is not present
     1128         (or not applicable because the selected representation does not have an entity tag).

     1075<t>
     1076   When more than one conditional request header field is present in a request,
     1077   the order in which the fields are evaluated becomes important. In practice,
     1078   the fields defined in this document are consistently implemented in a
     1079   single, logical order, due to the fact that entity tags are presumed to be
     1080   more accurate than date validators. For example, the only reason to send
     1081   both <x:ref>If-Modified-Since</x:ref> and <x:ref>If-None-Match</x:ref> in the same GET request is to
     1082   support intermediary caches that might not have implemented <x:ref>If-None-Match</x:ref>,
     1083   so it makes sense to ignore the <x:ref>If-Modified-Since</x:ref> when entity tags are
     1084   understood and available for the selected representation.
     1085</t>
     1086<t>
     1087   The general rule of conditional precedence is that exact match conditions
     1088   are evaluated before cache-validating conditions and, within that order,
     1089   last-modified conditions are only evaluated if the corresponding
     1090   entity tag condition is not present (or not applicable because the
     1091   selected representation does not have an entity tag).
     1092</t>
     1093<t>
     1094   Specifically, the fields defined by this specification are evaluated
     1095   as follows:
     1096   <list style="numbers">
     1097     <t>When <x:ref>If-Match</x:ref> is present, evaluate it:
     1098       <list style="symbols">
     1099         <t>if true, continue to step 3</t>
     1100         <t>if false, respond <x:ref>412 (Precondition Failed)</x:ref></t>
     1101       </list>
     1102     </t>
     1103     <t>When <x:ref>If-Match</x:ref> is not present and
     1104        <x:ref>If-Unmodified-Since</x:ref> is present, evaluate it:
     1105       <list style="symbols">
     1106         <t>if true, continue to step 3</t>
     1107         <t>if false, respond <x:ref>412 (Precondition Failed)</x:ref></t>
     1108       </list>
     1109     </t>
     1110     <t>When the method is GET and both <x:ref>Range</x:ref> and
     1111        <x:ref>If-Range</x:ref> are present, evaluate it:
     1112       <list style="symbols">
     1113         <t>if the validator matches, respond <x:ref>206 (Partial Content)</x:ref></t>
     1114         <t>if the validator does not match, respond <x:ref>200 (OK)</x:ref></t>
     1115       </list>
     1116     </t>
     1117     <t>When <x:ref>If-None-Match</x:ref> is present, evaluate it:
     1118       <list style="symbols">
     1119         <t>if true, all conditions are met</t>
     1120         <t>if false for GET/HEAD, respond <x:ref>304 (Not Modified)</x:ref></t>
     1121         <t>if false for other methods, respond <x:ref>412 (Precondition Failed)</x:ref></t>
     1122       </list>
     1123     </t>
     1124     <t>When the method is GET or HEAD,
     1125        <x:ref>If-None-Match</x:ref> is not present, and
     1126        <x:ref>If-Modified-Since</x:ref> is present, evaluate it:
     1127       <list style="symbols">
     1128         <t>if true, all conditions are met</t>
     1129         <t>if false, respond <x:ref>304 (Not Modified)</x:ref></t>
     1130       </list>
     1131     </t>
     1132   </list>
     1133</t>
     1134<t>
     1135   Any extension to HTTP/1.1 that defines additional conditional request
     1136   header fields ought to define its own expectations regarding the order
     1137   for evaluating such fields in relation to those defined in this document
     1138   and other conditionals that might be found in practice.
