Chris,
I tried this, but it does doesn't seem to work.
Using the <base href="" tal:attributes="href request/URL0"/>
it generates:
<base href="http://localhost:8080/path/to/www/index_html/" />
(without session data, and the "<a href="testlink">" is not translated)
I tried also <base href="" tal:attributes="href request/PATH_INFO"/>
which displayed the session data when called, but it now displayed only
<base href="/_ZopeId/98484417A0xKnA7xHio/path/to/www" />
- which means that after clicking a link it went to a level higher and it
did not find it.
Using this, I played with it a used more with combinations for href
replacements like:
- string:${request/SERVER_URL}${request/PATH_INFO}
- string:${request/SERVER_URL}${request/PATH_INFO}/
- string:${request/SERVER_URL}${request/PATH_INFO}/index_html
, but I have not found any solution, which would be completely stable and
compatible. If it works for you, could you possibly send me a *.zexp
example, which I could inspire from?
Thanks and regards, Lubos.
