$OHDR allows access to the request's outgoing headers, http://www.proxomitron.info/45/help/Matc....html#OHDR . In this case, requests to ad.doubleclick.net/ will be allowed when the referer matches http://www.imdb.com/images/a/ifb/doubleclick/expand.html*.

Code:

www.imdb.com/(*doubleclick$SET(1=adpath:0.)|$SET(0=a_jslink.))

What is the function of "doubleclick" before the $SET command and why is there an "or" separating them?

When "doubleclick" is part of the imdb URL's path, the adpath variable is set to allow access, $SET(1=adpath:0.). Otherwise the distasteful request would be blocked.
When "doubleclick" is absent, the "OR" allows me to specify $SET(0=a_jslink.) without allowing access to adpaths other that "doubleclick".
I could have used

Code:

www.imdb.com/*doubleclick$SET(1=adpath:0.)|www.imdb.com/$SET(0=a_jslink.)

If two lines like

Code:

www.imdb.com/$SET(0=a_jslink.)
www.imdb.com/*doubleclick$SET(1=adpath:0.)

, it's possible for the first to match and prevent the second from ever matching, see Limitations.. at http://www.proxomitron.info/45/help/Bloc...ation.html .

A space matches when there is and isn't space. The targeted addresses should not contain spaces. So, while a space might make the expression easier to follow it isn't necessary.

I may use a kind of outline format. The ### line is the rest of the thought that began in the ## line that preceeds it. Normally ## imdb would have been # imdb but I forgot.

It's just that when the desired content on a major site is blocked, some kind of "fix" seems warranted. In fact I've often wondered if there's not a broader solution to the filter set's issues with video. "Are you sure" alerts would be FAR preferable to having to bypass Proxomitron, clear cache and reload the page, which is what happens with video on a number of sites. And I'm a little perplexed by why no one else seems to have an issue with this.

Some users are probably a little perplexed that other users will allow access to doubleclick.

The Proxomitron can't filter by content quality. Ad servers host acceptable ads like movie trailers and unacceptable ads.

If we add a confirm

Code:

www.imdb.com/(*doubleclick $CONFIRM(Are you sure: doubleclick in path) $SET(1=adpath:0.)|$SET(0=a_jslink.))
ad.doubleclick.net/ $OHDR(referer:http://www.imdb.com/images/a/ifb/doubleclick/expand.html*) $CONFIRM(Are you sure: doubleclick in host) $SET(1=adurl_h:0.)

and if imdb uses doubleclick for all ads, you might see a lot of "Are you sure:"
