parsing a http request

[fhein]

I'm using this simple (and probably not so good) code to split up a http request:

Code:

 
if valid?: parse/all str [
copy method to " " skip
copy URI to " "
thru "^/"
some [
copy aname to ":" (append args aname) 2 skip
copy aval to "^/" (append args aval) skip
]
content: to end
][
print "stuff"
]

but now I want URI to only contain the the part up to "?" and put the rest of it in another var. For example:

/index.html?r=0&b=1

=>  URI="/index.html"  rest="r=0&b=1"

/index.html

=> URI="/index.html"  rest=""

Code:

>>s = "/index.html?r=0&b=1"
>>
>> parse s "?"
== ["/index.html" "r=0&b=1"]

Code:

>>s = "/index.html"
>>
>> parse s "?"
== ["/index.html"]

almost there for the second one, it just simply doesn't exist if you do it this way.
Hope this helps

hmm, that's not exactly what I'm trying to do.. you see the url is part of a longer string so I can't use the simple parse syntax. here's an example of what a request can look like:

"GET /index.html?a=1 HTTP/1.1
accept: */*
host: localhost

"



thanks anyhow though, and don't give up just yet I think I'll use a non optimal splitting solution so I can move on with the programming

"GET /index.html?a=1 HTTP/1.1
accept: */*
host: localhost

"

 

Well if the format is always this one, you could still use parse. :)

Code:

rule: [thru "GET" copy uri to " " (uri: parse uri "?")]
parse str rule
print mold uri

Problem is, does your string always has this format? :o)

well, the http request follows some basic rules (you can check the complete rfc at w3.org but it's huuuuge). I think I'll skip using parse though, because there are too many things I just want to ignore if they aren't relevant :\

the synthax is something like:

{method} {uri} HTTP/{version}crfl
{argname}: {argvalues}crlf
...more arg-pairs...
crlf
{possible content where I don't want automatic line-feed conversion}


I _hope_ that the lines in the header always are terminated by CRLF = #{0D0A} because that would make things alot easier for me
