I'm running a transparent proxy (squid) and DansGuardian to filter web searches. In DansGuardian, I rewrite Google searches so that SafeSearch is always forced on, regardless of what my (young) users may input as a search.

Is there any way of forcing the Yahoo equivalent SafeSearch through a URL rewrite in DansGuardian or Squid?

Hey Jimbo,

For the children then....
The dansqaurdian rules seem to employ a this = that format so...

This is my search for "porn" when yahoo safe search is turned on:
Again turned off...
Nude Celebrity safe search on
again off...
I'm getting the impression looking at the URLs that the safe search setting is not in the URL.
Perhaps a better way to do this with yahoo is create an account, log in and set your preferences to "Safe search" and "stay logged in for 30 days". Copy and paste that profile into the default browser and see if that works.

Hi dijetlo

Thanks for the response, you are right that if you set safesearch in Yahoo, it's not (in this instance) done by the search string....but in Google, I can EITHER set safesearch "globally", i.e. by logging on, and changing my profile, OR by adding to the search string.

You have correctly identified that I could set Safesearch globally by changing my profile, but what I really want to do is to add to each search string a command that forces safesearch for that search only...

To impose SafeSearch for Google or Bing, all you have to do is add the following to /etc/dansguardian/lists/urlregexplist (it might be in a different folder, but the name of the file will be urlregexplist)


#for google
#we add &safe=vss to the end of every search
"(^http[s]?://[0-9a-z]+\.google\.[a-z]+[-/%.0-9a-z]*/search\?.*)"->"\1&safe=vss"


#for bing
#similar, but &adlt=strict is the keyword
"(http[s]?://[0-9a-z]+.bing.com/images/search\?.*)"->"\1&adlt=strict"

but I can't see a way of doing it in Yahoo

Anyway, thanks for your thoughts....anyone else going to contribute to this thread?
