##############################################
# memory_replacement != memory_replacement_policy in "squid.inc" that is why it didn't stick in "squid.conf"!!!
			<fieldname>memory_replacement_policy</fieldname>
###############################################
			<description>The memory replacement policy determines which objects are purged from memory when space is needed.  The default policy for memory replacement is GDSF.  <p> <b> LRU: Last Recently Used Policy </b> - The LRU policies keep recently referenced objects.  i.e., it replaces the object that has not been accessed for the longest time. <p> <b> Heap GDSF: Greedy-Dual Size Frequency </b> - The Heap GDSF policy optimizes object-hit rate by keeping smaller, popular objects in cache.  It achieves a lower byte hit rate than LFUDA though, since it evicts larger (possibly popular) objects.  <p> <b> Heap LFUDA: Least Frequently Used with Dynamic Aging </b> - The Heap LFUDA policy keeps popular objects in cache regardless of their size and thus optimizes byte hit rate at the expense of hit rate since one large, popular object will prevent many smaller, slightly less popular objects from being cached.  <p> <b> Heap LRU: Last Recently Used </b> - Works like LRU, but uses a heap instead. <p> Note: If using the LFUDA replacement policy, the value of Maximum Object Size should be increased above its default of 12KB to maximize the potential byte hit rate improvement of LFUDA.</description>

I hope this gets updated into the package, so not everyone needs to edit these files by hand. ;)

fixed … thanks !

trendchiller

but i do not see any changes with ftp-browsing…
and although i'm familiar with squid i cannot get the point why to add the squid port 3128 th the safe-ports list ?

Tikimotel

Without the squid's own port, you would see empty image boxes.
With the port you are able to download and see the anthony-*.gif icons (but they're text-like in this release.)

trendchiller

ok, thanks…

Tikimotel

Ok you might want to fix the default icon directory too. :-[
I named it inside the squid.conf too, eventhough it's the same as with default for squid. (using squid.inc, below "error_directory")
"icon_directory /usr/local/etc/squid/icons"

( other configs say default is "/usr/local/squid/icons" )
It only works with FF, IE doesn't know what to do with a "localhost:3128" link.

Ok, I've now got IE and FF working with squid icons!!!
previous pic of FF was direct, no proxy… sorry.

Set "Visible hostname" to your router's name, in my case this is "pfsense".

trendchiller

the icons directory is already fixed…

still no changes to see for me :-[

visible hostname is a dns-alias...

here it does not show the icons you put in the screenshot, neither in ie7 nor in FF :-(

Tikimotel

hmm, I had to empty the local IE and FF caches to get it to work as in the uploaded pics.

If I set hostname back to localhost, my clients with FF and IE won't load the pics.
They can't find it on localhost…(is the clients own machine)
pfsense is what I choose on install as my firewall machinename and it resides in the /etc/hosts file on my firewall.
Furthermore I have dnsmasq (a.k.a DNS forwarder) add leases to the dns forwarder and the static mappings too.

trendchiller

ok,i got it… BUT: if I remove the squid-port from the safe-ports list, it shows me the icons, too...
even after deleting the local cache...
and every manual i looked up never told me to add the squid-port to the safe-port-list...

so i guess i'll removing it... for security reasons...
