Unfortunatelly I don't have definitive answers for these questions. There's more than one way to do it and the choice somewhat depends on what the underlying purpose of the bigger picture is. For instance: distributed design vs monolithic, quick implementation vs a more flexible one, low library dependencies vs linking dillo to a bigger set. Personally, I think that patching dillo with an integrated quick implementation of https (like Indan's) while we develop a more flexible dpi that provides at least the same, can be a good approach. I'll try to briefly comment your concerns: > Also, there seems to be one process for one connection, which makes hard > to implement SSL session cache. Yes, that happens with dpi filters. The idea in this case is to have an http dpi that's able to handle several connections at the same time (like the downloads dpi). That is: a dpi server instead of a dpi filter. With that scheme session cache is easy to implement. (and BTW much easier for the developer because he can arrange things much more freely than when patching inside dillo). > content-type (as above). The https dpi would need to listen the HTTP stream and so has access to the content-type sent by the remote https server. > Cookies Cookies will end being a dpi! Currently dillo enables cookies for the first instance only (this is old problem of sharing a single resource among several clients). Fortunately dpi solves this, as with the current bookmarks dpi server that can be shared by multiple running instances of dillo. When this port is done, the one-instance-only restriction for cookies will be gone. > POST POST data can be passed to the https dpi using dpip. This information is inside the DilloUrl. > Since https is http over ssl, it seems natural to use dillo's > http protocol implementation for these things (like i did with my https > proxy for dillo), but is it possible with dpi? Yes I agree with that reusing dillo's http may come handy. Now, dillo does http 1.0 only so having it done inside a dpi can also bring http 1.1 (as with wget and current https.c). The other interesting point is that the SSL/TLS library spec states that appart from making a socket secure, the details of handling the possible errors should be solved by the client application depending on the protocol and what it is being used for. So having a generic SSL/TLS gateway may look interesting but it can get tricky to implement. For intance: handshake_failure(40), bad_certificate(42), unsupported_certificate(43), certificate_revoked(44), certificate_expired(45), certificate_unknown(46), illegal_parameter(47), unknown_ca(48), are to be handled in different ways regarding what the protected protocol using SSL/TLS is, the transport circumstances and the user's choice. (ah, and all the alerts can have a "level" of fatal or not). With a gateway, having only the option of closing the connection is not enough. Question dialogs can be implemented in the gateway process itself though (a GUI inside the dpi), and you also have to take care of differentiating the protocols. With dpi, the questions and actions can be communicated to dillo with dpip or be made part of the dpi server. It provides more flexibility. Making SSL a part of IO, comes with the burden of having to develop all of this error handling knowledge inside the IO layer (making dillo grow in size and complexity). Including questions, actions a protocol differentiation. HTH Jorge.-

Hi everyone. This time i have a little patch for urls with white spaces, it converts them to correct characters (%20), it works well, just download the nav.diff.gz from my site and copy it to dillo/src directory: $ gunzip nav.diff.gz $ patch nav.c nav.diff Answare yes to the question that patchs mades to you.

Best wishes for year 2004
by Jorge Arellano Cid 31 Dec '03

31 Dec '03

Hi There, It's early in the morning here in Chile, and I know that in Europe the clock is around 4 to 6 hours ahead, hopefully still in time to send my greetings and best wishes to all the people scattered around the world that participate of dillo-dev. Somewhere inside this december the Dillo project completed four years of existence and continued development. Please excuse me for not displaying a birthday cake picture at the home page; I didn't have the time, but the will to share and celebrate the event still remains! I spent the last months of this year making the arrangements to be able to keep working on dillo the 2004, and hopefully more... It seems that these efforts will flourish and let me work through this new year with renewed energies and hope: let 2004 be a great year for the Dillo project! Cheers & Best wishes to all! Jorge.-

Cache expire header...
by Tom Lisjac 24 Dec '03

24 Dec '03

Hi All! I've written a small, Dillo friendly wiki/cms system in php that I'm hoping to release in a few weeks. During testing (today's cvs), I found that Dillo's cache wasn't expiring the dynamic pages. Here's the header I was initially using to disable client caching: header("Expires: Sun, 22 Mar 1998 20:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Pragma: no-cache"); header("Cache-Control: post-check=0, pre-check=0"); With this header, Dillo's stdout messages reported "bad clocks"... so I tried sending the same date for Expires and Last-Modified. Dillo's stdout came back with: "Forcing min expire 60 on >the url< instead 0". What does that mean? I really need the content of certain pages to expire immediately when viewed. Any suggestions for the correct header parameters would be greatly appreciated. Thanks! -Tom

sending referer
by Jan Stary 19 Dec '03

Hello, why does Dillo not send the referer header? Without it, I cannot use the http://validator.w3.org/check/referer link, as appearing on the bottom of my pages. This is the only problem which keeps mozilla on my machine. Thank you Jan
