Last_Modified and ETags

Hello,

I'm using mod_layout 3.2.1 on Apache 1.3 in some pages which i give some
informations for CSS and HTML compliance. But in this pages cache's  
headers information are missing (etag or last-changed) causing squid  
not to work on those pages.

I  took a look at the sources and found  in ``utility.c'' these lines  
disabled:

----

LAYOUT_EXPORT(void) print_layout_headers(request_rec *r, layout_conf  
*cfg) {
         ap_rflush(r);
         r->content_type = "text/html";
         ap_update_mtime(r, r->finfo.st_mtime);
/*      ap_set_last_modified(r);*/
/*      ap_set_etag(r); */

----

Does request_rec *r came from the original page? I mean, will  
apt_set_last_modified(r) return consistent value form the original  
page? Is there any good reason for these comments? I'm planning to  
use mod_layout with LastModified and ETag on and see if it works for me.


Thanks in advance.
