-<para>
- These are URLs that match something in one of
- <application>Privoxy's</application> block actions
- (<ulink
- url="../user-manual/actions-file.html#BLOCK"><quote>+block</quote></ulink>).
- It is meant to be a warning so that you know something has been blocked and
- an easy way for you to see why. These are handled differently than what has
- been defined explicitly as <quote>images</quote> (e.g. ads that are GIF image
- files). Depending on the URL itself, it is sometimes hard for
- <application>Privoxy</application> to really know whether there is indeed an
- ad image there or not. And there are limitations as to what
- <application>Privoxy</application> can do to <quote>fool</quote> the
- browser.
-</para>
-
-<para>
- For instance, if the ad is in a frame, then it is embedded in the separate
- HTML page used for the frame. In this case, you cannot just substitute an
- aribitrary image (like we would for a <quote>blank</quote> image), for an HTML
- page. The browser is expecting an HTML page, and that is what it must have
- for frames. Such situations can be a little trickier to deal with, and
- <application>Privoxy</application> may show the <quote>Blocked</quote> page,
- despite your best efforts.
-</para>
-
-<para>
- If you want these to be treated as if they were images, so that they can be
- made invisible, you can try moving the offending URL from the
- <quote>+block</quote> section to the <quote>+imageblock</quote> section of
- your actions file. Just be forewarned, if any URL is made
- <quote>invisible</quote>, you may not have any inkling that something has
- been removed from that page, or why. If this approach does not work, then you are
- probably dealing with a frame (or <quote>ilayer</quote>), and the only thing
- that can go there is an HTML page of some sort.
-</para>
-<para>
- To deal with this situation, you could modify the
- <quote><filename>block</filename></quote> HTML template that is used by
- <application>Privoxy</application> to display this, and make it something
- more to your liking. Currently, there is no configuration option for this.
- You will have to modify, or create your own page, and use this to replace
- <filename>templates/blocked</filename>, which is what
- <application>Privoxy</application> uses to display the <quote>Blocked</quote>
- page.
-</para>
-<para>
- Another way to deal with this is find why and where
- <application>Privoxy</application> is blocking the frame, and
- diable this. Then let the <quote>+set-image-blocker</quote> action
- handle the ad that is embedded in the frame's HTML page.

+<para>
+ There are potentially several factors here. First of all, the DNS resolution

+ merely initiates the process and hands it off, and then later reports
+ whatever the outcome was. And tries to give a coherent message if there seems

+ adding <quote>www.</quote> to the URL). In other cases, if
+ <application>Privoxy</application> is being chained with another proxy, this
+ could complicate the issue, and cause undue
+ delays and timeouts. In the case of a <quote>socks4a</quote> proxy, the socks

+ the <quote>messenger</quote> which is reporting whatever problem occurred

+ occurs on pages containing many (thousands upon thousands) of blank lines. The blank lines
+ are in the raw HTML source of the page, and the browser just ignores them. But the
+ pattern matching in <application>Privoxy's</application> page filtering

+CLASS="APPLICATION"
+>Privoxy</SPAN
+>
+ merely initiates the process and hands it off, and then later reports

+ to be a problem. In some cases, this might otherwise be mitigated by the
+ browser itself which might try some work-arounds and alernate approaches (e.g
+ adding <SPAN
+CLASS="QUOTE"
+>"www."</SPAN
+> to the URL). In other cases, if
+ <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN
+> is being chained with another proxy, this
+ could complicate the issue, and cause undue
+ delays and timeouts. In the case of a <SPAN
+CLASS="QUOTE"
+>"socks4a"</SPAN
+> proxy, the socks
+ server handles all the DNS. <SPAN
+CLASS="APPLICATION"
+>Privoxy</SPAN

+> This is probably a manifestation of the <SPAN

+ mechanism is trying to match against absurdly long strings and this becomes
+ very CPU-intensive, taking a long, long time to complete. Until a better
