Need some URL help

Hi list, I have a problem with downloading this URL: http://www.linuxtelephony.org/article.cgi?i=400&r=0 It seems the linuxtelephony.org returns something in the HTTP headers that I cannot successfully read with rebol. Here's my code (copy&paste into your rebol shell, but watch out for line breaks): REBOL [] ; This is the URL: http://www.linuxtelephony.org/article.cgi?i=400&r=0 insert-this: "GET /article.cgi?i=400&r=0 HTTP/1.0^/Host: www.linuxtelephony.org^/" port: open/lines [ scheme: 'tcp host: "www.linuxtelephony.org" port-id: 80 ] print "[We send:]" print form insert-this insert port insert-this header: make block! 10 while [ not empty? reply: first port ] [ if none? reply [print "Break!" break] parse reply [ [copy name [thru #":"] (name: load name) | copy name [to end] (print form name)] [copy value to newline | copy value to end] (if value [append header reduce [name value]]) ] ] either [ not empty? content: first port ] [content: copy port] [print EMPTY! ] close port print reduce [header content] halt ===== End code From other servers, this code is OK, but this linuxtelephony.org URL always crashes on me. Does anyone have a clue? Thanks, HY PS. The server seems to run Apache with PHP4: Server: Apache/1.3.33 (Unix) PHP/4.3.11-dev X-Accelerated-By: PHPA/1.3.3r2 X-Powered-By: PHP/4.3.11-dev Could this be a PHP bug?

Argh! I just hate it when errors aren't repeatable. But the behaviour is consistent on my side: I get a 302 redirect to some URL with a session ID in it, which will (probably set a cookie and then) redirect me back. This works with a browser, but not with rebol... Darn. Actually, I know that rebol will halt in the line while [ not empty? reply: first port ] [ and claim there is an out-of-index or past-end error. When I probe 'port, I cannot see anything irregular at that point. Thanks for trying anyway. HY On 23/01/06, SunandaDH-aol.com <SunandaDH-aol.com> wrote:

Thanks for the tip, but I now tried with different haeders (didn't even include the user-agent header on first attempts). I have experimented with both HTTP/1.1 and HTTP/1.0, kept-alive and closed connections, with and without specifying the host, with different user-agents and even from different IPs... And nothing seems to make any difference. I now get the 302 error on all attempts. The rebol console looks like this: [We send:] GET /article.cgi?i=400&r=0 HTTP/1.1 Host: www.linuxtelephony.org connection: close user-agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) HTTP/1.1 302 Moved Temporarily ** Script Error: Out of range or past end ** Near: not empty? reply: first port

OK, I'm a little bit closer to the problem now. I tried to download the same URL using 'read, and rebol hung. Setting on trace, I got an endless loop in parsing of the HTTP headers, so there definitely is something spooky going on there. I put the lot (trace produces kilometres of output) on this URL: http://www.babelserver.org/ strange.html I believe this is a bug. I'd like to look closer into it myself, but since 'read is native, I cannot peek into it, can I? And from the 'port object, (open/lines), I don't know how to get more information than what I have on the above mentionned URL. What should I do? Should I post it directly to Rambo?

Sure. The server behaves as it pleases, it seems. The error appears when you get a 302 redirect http response header. Which one occationally does, Sunanda seems to have gotten it on his third attempt. I get it *most* of the time, and when I get a 200 OK header, everything works just fine for me too. The server that responds to http://www.viahardware.com/ exhibits the same behaviour. (Exhibits? Is that an english way of speaking? Or does it smell like new-mowed grass?)

If they redirect only sometimes, it's probably some load balancing they're doing. On 1/28/06, Hallvard Ystad <hallvard.ystad-gmail.com> wrote:

Still, the problem isn't the forwarding, but that rebol isn't able to read the response. It hangs, or actually, as the trace log shows, goes into an infinite loop. With read/lines on an open 'port, it crashes. HY On 27/01/06, Graham Chiu <compkarori-gmail.com> wrote:

Hi Hallvard, I forgot to mention, that after the final Net-log line below, rebol hung for a long time, until this was printed: ** Script Error: Not enough memory ** Where: append ** Near: insert tail series :value
