Description

If you inspect the HTTP headers of a page generated by Tiki, it has an Expires header in the past:
Expires: Thu, 19 Nov 1981 08:52:00 GMT

Beside that, I also suggest to enable caching, at least in the Raw page display (tiki-index_raw.php?page=), it enables the browser to cache frequently used information by something like the AJAXLoad plugin and improves performance.
Now the Pragma header has:
Pragma: no-cache
And the cache-control header:
Cache-Control: no-store, no-cache, must-revalidate

Workaround

When using IIS as server; add in you web.config between </rules> and </rewrite> the next code:

Copy to clipboard
<outboundRules>
                <rule name="Remove Pragma" preCondition="tiki-index_raw.php">
                    <match serverVariable="RESPONSE_Pragma" pattern="(.*)" />
                    <action type="Rewrite" />
                </rule>
                <rule name="Add Caching" preCondition="tiki-index_raw.php">
                    <match serverVariable="RESPONSE_Cache-Control" pattern="(.*)" />
                    <action type="Rewrite" value="private, max-age=300" />
                </rule>
                <rule name="Remove Expires" preCondition="tiki-index_raw.php">
                    <match serverVariable="RESPONSE_Expires" pattern="(.*)" />
                    <action type="Rewrite" />
                </rule>
                <preConditions>
                    <preCondition name="tiki-index_raw.php">
                        <add input="{URL}" pattern="tiki-index_raw.php*" />
                    </preCondition>
                </preConditions>
            </outboundRules>
