What it does is take the command line options and HTTP headers and put them all in environment variables. I did this to facilitate shell scripted web pages. It works by adding : rfork E /bin/ip/httpd/populate_environment.rc $* to the top of any web serving scripts and then the HTTP Headers etc. can be accessed through /env the example script uses html_encode.sed, which is a very low quality cut and pasted html entity encoder (supplied) I'm also including url_encode.awk which is nothing to do with this but useful all the same For as long as I am on this IP address you can see it in action at http://pc1-nott2-3-cust35.not.cable.ntl.com/magic/http_info.rc suggestions / criticisms welcome Matt ------=_NextPart_000_015A_01C22EDC.5D6BE4B0 Content-Type: multipart/mixed; boundary="upas-hfrzxfyxbvubwzdqnztdapxqaa" Content-Disposition: inline This is a multi-part message in MIME format. --upas-hfrzxfyxbvubwzdqnztdapxqaa Content-Disposition: inline Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit The following attachment had content that we can't prove to be harmless.

Nice job setting it up. It will take me a while to take it all in. My reason for using php and Sablotron is to present web pages dynamically and keep content (XML) separate from style (XSL). Here is a link to a web site I have set up to experiment and learn with. Sorry that this does not directly pertain to Plan9 now but as I said, if I can find a way to accomplish the same thing with Plan9 I will give it a go. http://213.84.71.105/ On Fri, Jul 19, 2002 at 06:42:25PM +0900, arisawa@ar.aichi-u.ac.jp wrote: > >> Is httpd ported to Plan9?

Unfortunately, other obligations have prevented me from getting all of the bugs out. Does anyone out there want to take up the guantlet and finish the job? I put the sources in the public source tree, under contrib/i , and would be happy to correspond with, and lightly collaborate with, anyone willing to solidify the port. The current state is that it often works, but there is some kind of bug in the table layout code (and doubtless, other bugs). And perhaps the biggest problem, for a modern browser, is that it doesn't do javascript at all. The port was done before Javascript support got added to charon. - Howard Trickey howard@research.bell-labs.com From mboxrd@z Thu Jan 1 00:00:00 1970 To: 9fans@cse.psu.edu From: Ben Message-ID: Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 8bit References: <002e01c22f43$122a6dc0$0100a8c0@335400>, <004201c22f4b$6b5aca40$bf356887@bl.belllabs.com> Subject: Re: [9fans] The "i" browser Date: Mon, 29 Jul 2002 16:00:56 +0000 Topicbox-Message-UUID: d5201bf8-eaca-11e9-9e20-41e7f4b1d025 howard@research.bell-labs.com (Howard Trickey) wrote in message news:<004201c22f4b$6b5aca40$bf356887@bl.belllabs.com>... > I did a port of the inferno browser (charon) to > plan 9, and called it "i".

I've you've read any of my other posts, you'll have noticed that I'm looking for a good browser under Plan 9. Unfortunately, I can't access the public source tree, as I can't dial out (for now). (Any latest development on the Lucent WinModem drivers?) Anyway, would you be so kind as to e-mail me a copy of the sources? Thanks much!
