How Browsers (IE) understand file types. - ASP / Active Server Pages

Roberto

1) I have the following html code on the server:

<HTML>
....
.....
<BODY>
<A HREF = http://MyServer/MyDoc.doc> Click here to see the document</A>

When I click on the link How Internet Explorer understand that it's a Word
Document and It's necessary open it with Microsoft Word ? Is The extension
to give the necessary information to Internet Explorer ?
Where does IE look for the application to use to open the file on the server
? On the local registry ?
I have tried to rename Mydoc.doc in MyDoc.pdf and I have called

http://MyServer/MyDoc.pdf and the browser has opened Acrobat Reader but the
binary format is for Microsoft Word.

Does the Browser User an Http_Header sended automatically ? (for example
HTTP_FILE_NAME. ...IF IT EXISTS)

2)Now I have the following link:

http://MyServer/ReturnMyDoc.asp

It returns the binary data of MyDoc.doc file. Now I want to say to the
browser that the file is called MyDoc.doc (I don't want to use Content Type
= ms-application/msword) : is there a header to say this to Internet
Explorer ?

Thanks Rob.

The association is in the client system registry. Usually set up when you
install the application that is intended to view the document. look at .pdf
and AcroExch.Docume nt under hkey_classes_ro ot for an example.

Hi Rob,

Thank you Mark for your info. I thought I might expand on it a bit.

1)
IE knows which application to run based on the file's file extension (.doc
or .pdf) along with the content type (ms-application/msword). IE matches
these up with the local registry to determine which application to launch.

2)
Here the file extension is .asp. That means the content type must be used
for IE to distinguish what application to launch. You wrote that you don't
want to use content type either. That means IE will not know which
application to launch.

Thank you, Mike
