Hey there,
There is a way to force a fetch of a full object when a partial byte
range accrues.
You can take a look at the example here:
http://wiki.squid-cache.org/SquidFaq/WindowsUpdate#How_do_I_make_Windows_Updates_cache.3F
Which is intended for windows update but also applies for other downloads.
My recommendation is to use the options wisely to not consume too much
of the bandwidth without any real reason.

Thanks Amos,
Is there any way to cache pdfs?
Could the pdfs converted, so that they are cachable?
Or has the web-application to be changed?
Regard
Joachim

Betreff: Re: SQUID 3.3.8 doesn't cache files greater than 50KB
Hi,
thanks for the responses.
I looked into the strange behavior a little bit more in detail and noticed,
that only pdf-files are concerned.
All other files, also greater than 50k, are cached, only pdfs are not
cached.
In the squid.conf I have:
refresh_pattern ^ftp: 43200 0% 43200
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i \.(gif|png|jpg|jpeg|ico)$ 43200 0% 43200 override-expire
ignore-no-cache ignore-no-store ignore-private refresh_pattern -i
\.(iso|avi|wav|mp3|mp4|mpeg|swf|flv|x-flv)$ 43200 0% 43200 override-expire
ignore-no-cache ignore-no-store ignore-private refresh_pattern -i
\.(deb|rpm|exe|zip|tar|tgz|ram|rar|bin|ppt|doc|pdf|tiff)$ 43200 0% 43200
override-expire ignore-no-cache ignore-no-store ignore-private
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern (Release|Packages(.gz)*)$ 0 20% 2880
refresh_pattern . 0 20% 4320
In the access-log I found:

If I rename the file 1.pdf in 1.exe, it would work.

I think there was a bug fixed very recently to do with the fact that
`maximum_object_size` is ignored if it comes after `cache_dir` in the
conf.
If you switch the order or move use `cache_dir max-size=n` then it
should be alright.

Hi,
I installed a squid on an ubuntu 14 server.
In the access.log I get for files greater than about 50KB the error
code TCP_MISS_ABORTED and the files are not cached.
MISS is server being contacted for data.
ABRTED is the client giving up before the response happens.
Given that responses under 50KB happen:
* Look to your network for TCP "window scaling" issues.
* look for PMTUd issues (somebody blocking ICMP usually).
