GlimmerBlocker is no longer maintained and should no longer be used as web sites have migrated from using plain http to using https (i.e. encrypted) which prohibits modification by a proxy unless you resort to install custom SSL certiticates on the client.
You should use a browser extension instead.
It was made as a hobby project during 2007-2008 by Peter Speck. It features both a custom http server and http client and a Mac OS X control panel.
Google Drive has two bugs:
So the usual workaround for buggy apps to add hosts to the "Bypass" list doesn't work for Google Drive. Thus, there is no official/recommended way to get Google Drive to work when using GlimmerBlocker.
You should pester Google about those bugs so they will get fixed, e.g. in its forums.
There is one workaround, but I cannot recommend this for most users as it entails modifying important system files and using command line as root using Terminal.app
First, create a file named /etc/apache2/other/googledrive.conf with the following content:
ProxyRequests On <Proxy *> Deny from all Allow from 127.0.0 </Proxy>
Note: I've had trouble with apache not starting if I add a "Order Deny, Allow" line. My test showed that it uses this order by default, so I've left it out.
You can only create the file as root, so copy the above into the clipboard and run the commands:
pbpaste | sudo sh -c 'cat > /etc/apache2/other/googledrive.conf'
Verify the content of the file using:
It's very important that this command shows that the file has the above content.
Now start apache. There is no longer a option for this in the sharing control panel, so you need to run the command:
sudo apachectl restart
This will not keep apache running after a restart of the Mac, so you need to issue this command after each restart.
When Google has fixed the bugs, you should remove the above. Use the following commands:
sudo rm /etc/apache2/other/googledrive.conf sudo apachectl stop
