</font><font size="2" face="sans-serif"><br>
thank you for your thoughts on the topic. You're right: after testing a lot it really looks like the request for a CGI script does not trigger the SSI handler. We've got to go the perl-based way rather than SSI.<br>

Hmmm, good question!</font><font size="3" face="serif"><br>
</font><font size="2" color="#1F497D" face="Calibri"><br>
If you print an SSI instruction directly from the CGI script, does that get converted as expected? E.g. does</font><font size="3" face="Courier New"><br>
print '<!--#echo var="DATE_LOCAL" -->';</font><font size="2" color="#1F497D" face="Calibri"><br>
output a date, or '<!--#echo…'?<br>
<br>
I haven't used SSIs alongside EPrints, but if the above doesn't interpret the SSI instruction my guess would be the PerlResponseHandler used for CGI scripts within EPrints::Apache::Rewrite module.<br>
<br>
I find the diagram here: </font><a href="https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fperl.apache.org%2Fdocs%2F2.0%2Fuser%2Fhandlers%2Fhttp.html%23HTTP_Request_Cycle_Phases&data=04%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7C2f1ea4280b4844f3694908d9145d6477%7C4a5378f929f44d3ebe89669d03ada9d8%7C0%7C0%7C637563213608590594%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=W1hdyxmIJt3X8RCXBg0D0GKIKte1ZiWpEywMDG1YLJI%3D&reserved=0" originalSrc="https://perl.apache.org/docs/2.0/user/handlers/http.html#HTTP_Request_Cycle_Phases" shash="yLvOPEUXS6Y+fhwFguXDqEDGhX3zauvvWYJls2U8IxPGLvsAJfYOmS+H34PYE7QjBmfzRLB+lzPB9o+ZeH7rIWdx5IiiWcN/iI7YzgWgJzZR1anY9VNbKXhAeRY4U+Di3secxAKtQnPVCPlUArn+z9xCQNf7YSD2wOV212y2jeg="><font size="2" color="#0000FF" face="Calibri"><u>https://perl.apache.org/docs/2.0/user/handlers/http.html#HTTP_Request_Cycle_Phases</u></font></a><font size="2" color="#1F497D" face="Calibri"> useful
to try and work out what the difference might be between e.g. a static page+template being served compared to a cgi script.<br>
<br>
The request for a CGI script might not trigger the SSI handler - but you may be able to add it to the stack, or a different phase (or even the output handlers).<br>

<font size="2" face="Arial">Hi out there<br>
<br>
maybe stupid. maybe simple, maybe offtopic, maybe not: <br>
<br>
We found out, that Server Side Includes (SSI) inside phrase dynamic.xml or templates will not be interpreted by cgi-scripts like cgi/stats/report.
<br>
Scenario: We generate static code, push it into a simple textfile.ssi and try to include it in the template with
</font><font size="3" face="Courier New"> <!--#include virtual="/maintenance.ssi" --></font><font size="2" face="Arial"><br>
<br>
So, in a nutshell: HowTo tell CGIs/Apache to use SSI after CGI has done? We thought, we tried out everything in Apache conf.<br>
Any hint is appreciated #-)<br>
