[SLUG] mime type, enable .dwg in Apache

[Amanda Wynne]

I'm trying to make a hyperlink to an AutoCad .dwg file. A search on Google reveals the correct mime type to use is image/vnd.dwg which is in my mime.types file for Apache. In Mozilla I've added, under "helper applications", extension dwg, mime type image/vnd.dwg, handled by application C:\Program Files\AutoCAD LT 2000i\aclt.exe. I suspect I need to add an entry into httpd.conf about AddEncoding vnd.dwg dwg but I'm not sure about the syntax; or even if I'm on the right track here. When I click on the hyperlink, I get a screen full of garbage text. Can somebody point me in the right direction, or offer some hints? Thanks. Amanda
