AW: [squid-users] SQUID 3.3.8 doesn't cache files greater than 50KB

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

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.

Best regards
