How to allow cacheing?
My cocoon app, under tomcat, places "Pragma: No-cache" in it's response
headers.
How can I remove that on certain responces? Maybe this is a tomcat
question?

ESQL : creating dynamic elements ?
Posted by julien bloit <Ju...@ircam.fr>.
I'm building a database request using ESQL. Let's say I have a table with
two columns in the table i'm requesting. This is the xsp snippet I use to
get the results from the request :
<esql:results>
<esql:row-results>
<first_table_col_1>
<esql:get-string column="1"/>
<xsp:attribute name="first_table_col2">
<esql:get-string column="2"/>
</xsp:attribute>
</first_table_col_1>
</esql:row-results>
</esql:results>
This works, but as I want this code to be dynamic in order to be used with
other tables, I need my column element name (the currently static
"<first_table_col_1>" element) to be created with the requested column name.
The same logic would apply for the 'name' attribute in the 'xsp:attribute'
element. I don't know if this is possible, using the esql logicsheet.
any ideas?
Thank you,
Julien

In searching around I found many, many write-ups on making sure pages are
*not* cached, by adding "Pragma: no-cache" in various ways. The
interesting thing is that my setup seems to always send a "Pragma:
No-cache" in its responses even though I have done nothing to add that
myself.
I did find something that works though. I added:
<xsp:logic>
response.setHeader( "Cache-Control", "max-age=3600" );
response.setHeader( "Pragma", "cache" );
</xsp:logic>
To the specific xsp file in question. Now I know that "Pragma: cache"
is an invalid header item, but it does in fact get into my response header
and it *replaces* the "Pragma: No-cache"!
I'm sure "Pragma: cache" is almost certainly ignored, but at lease
"Pragma: no-cache" isn't there. The overall affect is that the page does
in fact get cached on the particular browser the user wants to use.
Success! For now...

has something about this pragma, maybe you can rip out a working
solution that suits your need (seems to require 2.1x though).
