[opencms-dev] preview problem, quick fix

[Martin Leja]

hi alex,

your quick-fix seems to fix the IE preview problem, unfortunately i noticed
a drawback.
With only the modified version of the file ...\Tomcat
4.1\webapps\opencms\WEB-INF\oclib\opencms.jar (opencms version 4.6.1)
changed, all IE previews take a long time for online and offline files.
On my pentium3 650MHz it takes about 20 seconds until an url like
http://localhost:8080/opencms/opencms/system/workplace/action/explorerShowRe
source.html?url=/opencms/opencms/somefile
is mapped to http://localhost:8080/opencms/opencms/somefile and finally gets
displayed.

Making previews with mozilla works as usual, nearly no delay.
Any idea how to fix this?
