can you give an exmple, please? i jsut don't get it, sorry.

furthermore, the documentation on the site says
dllfunction HTTP_PostFile(id,url_str,file_str); while the wdl that comes with the pac states
dllfunction HTTP_PostFile(id,url_str,file_str,var_str); whithout explaining var_str.

regarding the 5.5->6.4 problem, it works fine with 6.3.
