- * Revision 1.9 2002/11/04 04:35:22 mh
- * merge media InputStream changes from MIR_1_0 branch
- *
- * Revision 1.7.4.3 2002/11/01 05:38:20 mh
- * Converted media Interface to use streams (Java IO) instead of byte buffers of
- * the entire uplaoded files. These saves loads of unecessary memory use. JAI
- * still consumes quite a bit though.
- *
- * A new temporary file (for JAI) parameter is necessary and is in the config.properties file.
- *
- * A nice side effect of this work is the FileHandler interface which is
- * basically a call back mechanism for WebdbMultipartRequest which allows the
- * uploaded file to handled by different classes. For example, for a media
- * upload, the content-type, etc.. needs to be determined, but if say the
- * FileEditor had a feature to upload static files... another handler wood be
- * needed. Right now only the MediaRequest handler exists.
