Can't reload the page by F5

Hi


i use the WWWOFFLE Version 2.9 under Debian testing.
But I couldn't reload the page in my browser by pressing F5 (reload
button). As far as I know, after the press that button the browser will
sent to wwwoffle the string Cache-Control: no-cache or Pragma: no-cache
and after that wwwoffle should download new copy of page from Internet.
In my case I see old version of page. It's extract from my config

 cookies-force-refresh = yes
 pragma-no-cache         = yes
 cache-control-no-cache  = yes
 cache-control-max-age-0 = yes
 request-changed       = 10d
 request-changed-once  = yes
 request-expired       = yes
 request-no-cache      = yes
 request-redirection   = no
 request-conditional   = yes
 validate-with-etag    = yes
 try-without-password  = yes
 intr-download-keep    = no
 intr-download-size    = 1
 intr-download-percent = 80
 timeout-download-keep = no
 keep-cache-if-not-found = no
 request-compressed-data = yes
 request-chunked-data    = yes

Anybody help me ?
