Hi Torsten,
we had some issues with (idiotic configured) firewalls which block files
of type .gz.
I first used .js.gz as file extension.
Regards.

Hi, Dietrich,
I like your solution but I have two questions:
- I think, in case of IE6 the time until application start will increase
because of loading the compressed content before loading of uncompressed.
Would be in my case between 10% and 20%, I think that's ok. Beyond this, is
it thinkable, that the browser crashes caused of the sensless code?
- Is there a reason not to use gz as extension?
Cheers
Torsten

Hello List,
I want to give back some information how I succeded to serve a staticaly
compressed qooxdoo.js file with a fallback for loading the non
compressed version.
Some firewalls are configured to filter compressed files so the users
behind this firewall have no access to the compressed qooxdoo.js. The
compressed file is qooxdoo.jsz which was compressed by gzip. Here is
what I did.
1) Configured apache through .htaccess to send back the right mime type:
AddEncoding x-gzip .jsz
AddEncoding gzip .jsz
2) Included the following lines in my qooxdoo-ish html files:
<script type="text/javascript" src="/qooxdoo/public/qooxdoo.jsz"></script>
<script type="text/javascript" language="JavaScript">
if( typeof(QxMain) == 'undefined' ) {
document.write("<SCR" + "IPT LANGUAGE='JavaScript'
SRC='/qooxdoo/public/qooxdoo.js' TYPE='text/javascript'><\/SCR" + "IPT>");
}
for the new namespace branch the line should be:
<script type="text/javascript" src="/qooxdoo/public/qooxdoo.jsz"></script>
<script type="text/javascript" language="JavaScript">
if( typeof(qx) == 'undefined' ) {
document.write("<SCR" + "IPT LANGUAGE='JavaScript'
SRC='/qooxdoo/public/qooxdoo.js' TYPE='text/javascript'><\/SCR" + "IPT>");
}
The paths to the qooxdoo.js and qooxdoo.jsz have to be adapted according
to your configuration.
The first script tag tries to load the zipped file. If this gets its way
to the clients browser and the client is able to uncompress the file and
interprete it there should be a object named QxMain. If this object is
undefined we asume that there was an error loading and running
qooxdoo.jsz.
The second script tag adds dynamically a script tag through
document.write which then tries to load the uncompressed qooxdoo.js.
Hope someone finds this usefull.
