| Subject: | AxAddOutputTransformer w/ cached content bug |
Hi,
apache conf file extract:
<AxMediaType screen>
<AxStyleName index>
AxAddProcessor text/xsl /test/test.xsl
AxAddOutputTransformer MyFilter::handler
</AxStyleName>
</AxMediaType>
with AxCacheDir unset this runs ok but when I set AxCacheDir a zero
length reply is returned from the server.
The exit point from Cache.pm is line 247:
if ($doit) {
AxKit::Debug(4, "Cache: Transforming content and printing to browser");
$r->pnotes('xml_string',$self->read());
return OK; # upstream deliver_to_browser should handle the rest
}
but in Axkit.pm this is not handled
I found that the the changes in the patch below seem to fix this
problem, but potentially break other AxKit code ;)
Regards,
George.
