[users@httpd] Apache + Squid Proxy: AH01991: SSL input filter read failed

["chiasa.men" <ch...@web.de>]

Hi,
my apache is behind a squid proxy which is configured like that:
https_port 3128 accel cert=/cert.pem key=/cert.key defaultsite=ww1.example.com 
vhost 
acl server20_domains dstdomain ww1.example.com ww2.example.com 
http_access allow server20_domains 
cache_peer server20 parent 443 0 no-query originserver name=server20 
login=PASSTHRU ssl sslversion=6 
cache_peer_access server20 allow server20_domains 
cache_peer_access server20 deny all 

The idea was to send ww1 and ww2 to server20 which is hosting an apache 
webservice for both sites. 
It works but each time I visit one of those sites the following messages 
appear in apache's logs: 

[00:00:39.641665] ---

The corresponding squid access.log entries would be: 
[00:00:39] "GET https://ww1.example.com/a/ HTTP/1.1" 503 4033 "-" "ua" 
TCP_MISS:FIRSTUP_PARENT 
[00:00:39] "GET https://ww1.example.com/some.js HTTP/1.1" 304 240 "https:// 
ww1.example.com/a/" "ua" TCP_MISS:FIRSTUP_PARENT 
[00:00:39] "GET https://ww1.example.com/someother.js HTTP/1.1" 304 239 
"https://ww1.example.com/a/" "ua" TCP_MISS:FIRSTUP_PARENT 
[00:00:39] "GET https://ww1.example.com/more.js HTTP/1.1" 304 241 "https://

[00:00:39] "GET https://ww1.example.com/a.png HTTP/1.1" 304 241 "https:// 
ww1.example.com/a/" "ua" TCP_MISS:FIRSTUP_PARENT 


You can see that approximately after 5s the timeout happens. Is it a message 
to worry about? (it is just "info" labled) Why does it occur?

I sent basically the same problem to squid's mailing list because I supposed 
squid was the problematic part here. But since they suggested apache could be 
the weirdo, I'm asking here
Thanks for your help
