[dundee] Squid Update Accelerator

[Robert Ladyman]

To those of you (Roddy and Andy, I think) to whom I was wittering about this, 
here is the link:

http://update-accelerator.advproxy.net/

It says it needs 'ipcop 1.4.x' (see the FAQ section), but if you read the 
installation script you can see that this is only because files are in 
specific locations and need to be maniputlated for IPCOP - in reality, all the 
work is done by /usr/sbin/updxlrator with an entry in squid.conf of:

redirect_program /usr/sbin/updxlrator
redirect_children 5

updxlrator uses regexs (mostly) to check the urls and then places matching 
files into the relevant location. It handles mirrors as well (VERY handy for 
OpenSuse and probably for other distros).

For example (it doesn't wrap well!):- 

# -----------------------------------------------------------
#  Section: Windows Update / Windows Downloads
# -----------------------------------------------------------
if (
    (($source_url =~ m@^http://[^/]*\.microsoft\.com/.*\.(exe|psf|msi|msp|msu|
dmg|cab)$@i) ||
     ($source_url =~ m@^http://[^/]*\.windowsupdate\.com/.*\.(exe|psf|msi|msp|
msu|dmg|cab)$@i))
&&   ($source_url !~ m@^http://[^/]*\.microsoft\.com/.*(/autoupd|
selfupdate/).*\.cab at i)
&&   ($source_url !~ m@\&@)
   )
{
$xlrator_url = &check_cache($source_url,$hostaddr,$username,"Microsoft",
$unique);
}


This one shows mirror usage...

# -----------------------------------------------------------
#  Section: Linux Downloads
# -----------------------------------------------------------
if ($source_url =~ m@^[h|f]t?tp://[^?]+\.(deb|rpm|gz)$@i)
{
$xlrator_url = &check_cache($source_url,$hostaddr,$username,"Linux",$mirror);
}
