Redirect http to https of the same domain.

[vlad_s]

Hello! Here's a filter that does not work:

Code:

{ +redirect{s@^http://@https://@} }

.example.com

More precisely, the browser says that "incorrect redirection on the page." In the console, you can see that the redirect happens several times on the same page. I sort of understand the problem, I got some kind of fixated redirect, but I do not understand how to solve it. Using rewrite and the client-header-filter in. From help's Privoxy I do not really understand how to do it.

Due to the operation of ProxHTTPSProxyMII, the redirects action cannot be performed. It turns out an endless redirect. For example http://example.com to https://example.com. If you redirect to another site, then there is no problem, http://example.com to https://example2.com. How can you solve this problem? You can try to make filters for Privoxy, but I acted differently. On top of that, I use a squid proxy server, he also knows how to redirect. Add the following lines to its config:

Code:

acl PORT80 localport 80
acl MYSITE dstdomain "/etc/squid/redirect"
http_access deny PORT80 MYSITE
deny_info 301:https://%H%R MYSITE

Create a redirect file at the specified path and fill in the necessary sites, one line - one site. Perform "squid -k reconfigure". We use. Thanks .

ProxHTTPSProxyMII's front server adds the request header

Code:

Tagged:ProxHTTPSProxyMII FrontProxy/

.
So "Tagged" requests are HTTPS requests.

To avoid the loop, Privoxy must not redirect request that contain the "Tagged" header.

At https://www.privoxy.org/user-manual/actions-file.html , I see

Quote:8.4.4. The Negative Request Tag Patterns
To match requests that do not have a certain request tag, specify a negative tag pattern by prefixing the tag pattern line with either "NO-REQUEST-TAG:" or "NO-RESPONSE-TAG:" instead of "TAG:".

Negative request tag patterns created with "NO-REQUEST-TAG:" are checked after all client headers are scanned, the ones created with "NO-RESPONSE-TAG:" are checked after all server headers are scanned. In both cases all the created tags are considered.

I would try adding a "NO-REQUEST-TAG:" command for Tagged:ProxHTTPSProxyMII FrontProxy/ to the filter.

I will leave the syntax to others.

Not quite clear how to do this? Filters sequence and actions?

Me too. You have been warned.

After installing Privoxy 3.0.28, I added

Code:

{ +redirect{s@^http://[email protected]://prxbx.com@} }
NO-REQUEST-TAG:.*?Tagged

to the end of user.action.

I think it works? There is no loop and Privoxy's log showed:

Code:

{ +redirect{s@^http://@https://@} }
NO-REQUEST-TAG:.*?Tagged

also works for me but will redirect sites that don't support https.

Yes, it works, but in my example only with sites specified in the file /etc/squid/redirect, i.e. better selectively.

[vlad_s]

The construction doesn't really work, example:

Code:

{ +redirect{s@^http://[email protected]://nnmclub.to@} }
NO-REQUEST-TAG:.*?Tagged
nnmclub.to/

Privoxy log:

Code:

2019-06-08 22:53:39.193 7fa0e2ffd700 Redirect: pcrs command "s@^http://[email protected]://nnmclub.to@" didn't change "http://bt4.rutracker.cc/ann?pk=xxx".

Or I do not understand something.
