Abe rule blocking some Google search results, is this normal

Post by johnscript »

I was trying something with ABE and observed that this rule

Code: Select all

USER rule:
Site *.informaction.com
Accept from SELF
Deny
prevents google search results with the keyword "informaction" from being opened, meaning that if I click directly on the links in the search page, they will be blocked by ABE

Code: Select all

[ABE] <*.informaction.com> Deny on {GET https://forums.informaction.com/viewforum.php?f=7 <<< https://encrypted.google.com/search?output=search&sclient=psy-ab&q=noscript+forum+&btnG= - 6}
whilst I can still copy/paste such links in a new tab and open them.

Is this normal?

Why ABE thinks that clicks on a search result from google should be intercepted by the above rule?
Is that possibly because of some tracking header/cookie that google is adding to its search results?

Yes it's normal and expected. ABE is a CSRF prevention tool and if it didn't work this way then CSRF would be as simple as redirection of the main document and/or offering you a link to click on.
Use Deny INC instead of just Deny - or, alternatively, add .encrypted.google.com (note the leading dot) to the end of the Accept line.

You could also allow anonymous GET:

Code: Select all

Site *.informaction.com
Accept from SELF
Deny INC
Anon GET
Deny

True religion, which dares to acknowledge death and challenge the way we live, is an attempt to wake up.
