IIS6 and downloadable JAR file

IIS >> IIS6 and downloadable JAR file Hi IIS gurus,

I use IIS as download server for a Java based application (DoJa for
mobile phone). How it works : the phone download a package descriptor (a
.JAM text file), this file contains JAR package URL.

Phone downloads well both files on a Apache plateform but it refuses to
download files on a IIS/6 plateforme. MIME Type are the same, content
expiration disabled or enabled, i have the same behavior.

I compare headers between IIS/6 and Apache with a simple
GET /file.jar HTTP/1.1 (with JAM, i have the same scenario)

The only difference i see is X-Tag header.
Binary data are identical.

Any idea why cellular phone refuse to download the files ?
J'ai comparé les headers, en dehors du X-Tag, rien ne différencie l'un
de l'autre. Y a t il un moyen de supprimer ce header ?

IIS >> IIS6 and downloadable JAR file Sounds like a problem with your client since you can retrieve it with
another client. It is not clear in your comparison, but I want to know if
the Apache response headers are delimited by "\n" or "\r\n".

In your comparison, I see that Content-Type: and Age: headers are different
between the two servers, in addition to the X-Pad header. Why? I do not
know if it makes a difference to your client or not.

IIS >> IIS6 and downloadable JAR file Your MIME type is not the same, IIS returns application/java-archive while
Apache returns text/plain.

Phone works with text/plain on Apache.
I tried also with MIME application/java-archive, phone refuses to download.

I agree with you, it sounds like a client problem.
I the 4 samples below, it is more clear.

I tested with the same Content-Type, Age and X-Pad.
On the phone, only the Apache version works :(

Throught Wget i got (it is important to notice that it is *through*
Wget, i hope it reflects raw data captured).

CR = <US-ASCII CR, carriage return (13 or 0D)>
LF = <US-ASCII LF, linefeed (10 or 0A)>

Now this work.
How do i (and a good advice!) solve it ?

I wrote a download.aspx ASP.NET script that read JAM file binary and i
output it using Response.WriteFile().

IIS >> IIS6 and downloadable JAR file I would say that's your problem, you need to change IIS' MIME type for your
file to text/plain.

It does not work with text/plain on IIS/6.

Antoine.

IIS >> IIS6 and downloadable JAR file Can you use NetMon (network sniffer included with Windows Server 2003) and
get a capture of what is returned in the successful case with ASP.Net as
well as unsuccessful case ? That would help tremendously in figuring out
what the phone client is not agreeable with.
