SQUID range_offset_limit - understanding problem

[Nachtfalke]

Hi,

I read in the docs abou squid and caching windows updates. I read on squid-cache.org abot range_offset_limit -1 which forces squid to download the complete file.
If I do NOT use range_offset_limit -1 then it is like range_offset_limit 0 which means no download.

Now my question is, if I use different refresh_pattern, should I use after every line again range_offset_limit -1 ?

Example:

refresh_pattern -i .*microsoft\.com/.*\.(cab|exe|msi|msp) 86400 100% 86400 reload-into-ims;
range_offset_limit -1;
refresh_pattern -i .*windowsupdate\.com/.*\.(cab|exe|msi|msp) 86400 100% 86400 reload-into-ims;
range_offset_limit -1;

or is it enough with:

refresh_pattern -i .*microsoft\.com/.*\.(cab|exe|msi|msp) 86400 100% 86400 reload-into-ims;
refresh_pattern -i .*windowsupdate\.com/.*\.(cab|exe|msi|msp) 86400 100% 86400 reload-into-ims;
range_offset_limit -1;

Thanks for helping me.

Hi,

I found out, that the first part is nonsense.
one times "range_offset_limit -1" is enough.

Further I found out, how to cache kaspersky updates:

refresh_pattern -i .*kaspersky\.com/.*\.(.*) 1440 100% 1440 reload-into-ims override-expire override-lastmode;
refresh_pattern -i .*kaspersky-labs\.com/.*\.(.*) 1440 100% 1440 reload-into-ims override-expire override-lastmode;

For me this works - I think.
