Subject Re: zip serializer gives zero lenght output with large file
Date Wed, 20 Jul 2005 15:11:55 GMT
I tried a little bit different approach.

I wrote a xsl that prepend and append  zip tags to data, then I
serialize with zip serializer.

The result is the same. :-(.

I'll try to modify xsp.

Thanks

Alberto
