I have left this tombstone entry for historical interest.
Usually refers to software to speed up web access. Sometimes it is provided by your
ISP (Internet Service Provider) at extra cost. Google once offered the Google
Accelerator that worked only with Internet
Explorer and Firefox. It only works
in W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32 and W10-64. The Google Accelerator on the client end is a plug into
your browser and the server end is a massive farm of caching servers.
Google’s accelerator used several tricks:
- Google servers cache common webpages and images. If somebody else using Google
has recently examined a web page you want to look it, the Google accelerator will
automatically fetch it from a fast Google cache server. This works on top of any
caching your ISP or browser software does.
- Google servers deliver cached web pages in compressed format so they transmit
- The Google accelerator preemptively requests pages it thinks you might want to
look at in future, in the background, when it has nothing better to do.
- The benefit to you is you get faster Internet access.
- The benefit to Google is they get to see which pages everyone is using most.
This will help them in their rankings and deciding how often to respider. This will
lead to better quality lookup.
- The benefit to the Internet community is the entire Internet is used more
efficiently, spending less and getting more value out of the same equipment.
- The upside of this to websites is that as traffic grows you don’t have to
buy as many bigger servers. If people access your site through the Google
accelerator, it is Google shouldering the bigger load.
- Beware. The Google web accelerator proxy drastically slows down Java Web start
unless you configure jawaws.exe to use a direct network
- The downside of this to you is Google gets to look over your shoulder at
everything you do, including passwords, your pornography viewing habits and your
political tastes. It is very big brotherish, but in principle nothing your
- The downside of this to websites is that they will no longer get accurate hit
counts. Google can fetch a page once and the feed its copy to 1000 people. If Google is not very careful, they will befuddle
various affiliate click through
programs, since clicks won’t register if they are served from cache.
- A major downside is that Google has implemented its beta accelerator only for
Internet Explorer and Firefox. This could be the death knell for all other browsers
if the Google Accelerator catches on. For other browsers running on Windows,
you’ll need to manually configure your proxy settings to 127.0.0.1:9100 for HTTP (Hypertext Transfer Protocol)
connections. This not rocket science, but enough of a hassle to block the average
- If this catches on, it will make Google a monopoly.
Preparing To Use the Google Accelerator
To use the system, an
end-user had to download and install the Google accelerator. A website should review
the freshness dates they apply to all documents served. If they are too short Google
can’t cache them. If they are too long, the Google will be serving old pages on
