File downloading problem

[tonyo <to...@no-log.org>]

Hi,
 
I'd like to make some Word and PDF files downloadable from my
application, based on Cocoon 2.1.2 / Tomcat 4.1.18.
Here is the problem I meet:
- The first click on the link gives the following message :
Internet Explorer cannot download toto.doc from localhost
Internet Explorer was not able to open this Internet site. The requested
site is either unavailable or cannot be found. Please try again later.
- If I click 'OK' and try again, then the downloading comes successful.
 
I know that this question has already been raised before, but the
proposed solutions (consisting in adding a set-header action before the
reader in the map:match) didn't solve my problem.
 
Here is an extract of my sitemap:
<!-- Word files -->
<map:match pattern="resources/**.doc">
    <map:read mime-type="application/msword" src="resources/{1}.doc"/>
</map:match>
<!-- PDF files -->
<map:match pattern="resources/**.pdf">
    <map:read mime-type="application/pdf" src="resources/{1}.pdf"/>
</map:match>
 
Many thanks in advance for your help
 
Antoine
