Hi everybody,

I found my mistake !! The process is not good. This is the correct process : browser (localhost:8118) <-> (localhost:8118) privoxy <-web-> server [and] (localhost:8888) stunnel (server:443)

So with only privoxy like proxy in my Firefox config - when I ask http://server/page.html , data is modified by privoxy - when I ask https://server/page.html, data is transmitted by privoxy - when I ask http://localhost:888/page.html data is modified by privoxy and the real data transmitted is https://server/page.html , stunnel managing SSL between localhost and server. My new config : [https] accept = 8888 connect = server:443

In fact, it was the stunnel main function that I didn't understand. Sorry :)

Thanks to exos, and hope it will help someone,

Xavier

I wan to customize web page before viewing by my browser Firefox. With "privoxy" (www.privoxy.org) I can modify (proxy filter) HTTP web page, but not HTTPS pages. So, I want to use stunnel, to transfer HTTPS in HTTP between my proxy and server, like this :

browser (8118) <-> (8118) privoxy (8888) <-> (8888) stunnel (server:443) <-web-> server

This is my stunnel.conf : ---------------------------------------------------- ciphers = RC4-MD5:DES-CBC3-SHA verify = 0 debug = 7 client = yes

[https] accept = 8888 connect = server.server.com:443 TIMEOUTclose = 0 ----------------------------------------------------

Note the first "Socket closed on read". I think the problem is there. The web reply is "Bad Request (Invalid URL)"

Where did I do a mistake ?

Thanks for answer,
