ASP and VBscript with WebDatablade and DDW

Hi I am working on Windows NT 4 with SP3, Option Pack 4 and IIS 4.0 with IDS/UD 9.14 TC6, WebDataBlade 3.32.TC5 and DDW Release 1.1. After putting a new line in wbextensions with the following contents Extension: asp Name: Application Page source_table: wbPages super_type: text sub_type: html id_column: ID content_column:object retrieval_method: 1 path_column: path webdriver recovers the Application Pages with extension asp, but the IIS does execute neither VBscript nor ADOBD. If I change sub_type to "asp" Iexplore presents the download program. Also I would like to know how to put these super_type, sub_type field, taking in account, that "application/ms-word isn't between mime types. I guess it's a Windows NT configuration problem in relation with IDS/UD, but I don't know what to do further. After install I received permanently the error code 502 (bad gateway) and it has gone off now, but i can't say why. Any help would be greatly appreciated heidi
