[EP-tech] Antwort: RE: Short question about SSI in dynamic CGI output



CAUTION: This e-mail originated outside the University of Southampton.

Dear John

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.

Kind regards
Jens

Hmmm, good question!

If you print an SSI instruction directly from the CGI script, does that get converted as expected? E.g. does
print '<!--#echo var="DATE_LOCAL" -->';
output a date, or '<!--#echo?'?

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.

I find the diagram here: https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fperl.apache.org%2Fdocs%2F2.0%2Fuser%2Fhandlers%2Fhttp.html%23HTTP_Request_Cycle_Phases&amp;data=04%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7C422e823a95fa4c0411de08d91153ac71%7C4a5378f929f44d3ebe89669d03ada9d8%7C0%7C0%7C637559873335504218%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=za8PSEApPgQmW31mf7q1YU63gd7DZun9%2BMDzlkcTYH4%3D&amp;reserved=0 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.

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).

The start of this page: https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwiki.eprints.org%2Fw%2FHow_to_enable_server_side_includes&amp;data=04%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7C422e823a95fa4c0411de08d91153ac71%7C4a5378f929f44d3ebe89669d03ada9d8%7C0%7C0%7C637559873335504218%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=4cSiZTMV0vKmlY5MCVjRbClzf2nVt5T358fz%2FwJP3Pw%3D&amp;reserved=0 indicates that someone has been down this path before:
"If you want to add dynamic content to the template you should do this via a template part in cfg.d/dynamic_template.pl"

They possibly included a maintenance.ssi file using perl-based methods rather than SSI methods?

Cheers,
John

Subject: [EP-tech] Short question about SSI in dynamic CGI output

CAUTION: This e-mail originated outside the University of Southampton.

Hi out there

maybe stupid. maybe simple, maybe offtopic, maybe not:

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.
Scenario: We generate static code, push it into a simple textfile.ssi and try to include it in the template with  <!--#include virtual="/maintenance.ssi" -->

So, in a nutshell: HowTo tell CGIs/Apache to use SSI after CGI has done? We thought, we tried out everything in Apache conf.
Any hint is appreciated #-)

Kind regards
Jens
