[users@httpd] Headers not present in response

Hi,
I've a strange problem about client-caching.

I'm comparing the responses of 2 webservers I'm administrator .
    - same os (Red-Hat 7.2, kernel 2.4.18-19.7.xsmp)
    - same httpd (1.3.27, last security patch applied)
    - not same machine (one compaq g2 and one 1850r)

The 2 httpd.conf are equals (cp and some minor changes : name of vhosts)

One one of the 2 servers, I think there are missing headers in responses :

eg (same browser, empty cache):

Request Server 1 (ok):

GET /temp/test_cache.html HTTP/1.0
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/tiff, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*

Request Server 2 (ko):

GET /temp/test_cache.html HTTP/1.0
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/tiff, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*
Accept-Language: fr

Host: preprod.clementine.orangecenter.com

Response Server 1 :

Response Server 2:

-----------------------------------------

As you can read, I can't find the headers Last-Modified, ETag, and Accept-Ranges in the Server 2 response.

I really don't understand this,
Has someone any idea ?

Thanks
