http - help

[anthony]

I am trying to use get http: to access a web site and parse the html
returned.

I open a socket and send a request across of the form
GET address http/1.0 where address is the specifics i am trying to log
onto.

the code works with web sites such as
"http://www.statistics.gov.uk/instantfigures.asp"
The http protocol header is removed.
The connection onto the socket is made on "www.statistics.gov.uk"
and the get is done on hthe address GET "/instantfigures.asp" http/1.0.

This is successful and the html is successfuly returned.

However, when i try to do exactly the same with the following web site.
"http://epp.eurostat.cec.eu.int/port...t=EUROIND&root=EUROIND/shorties/euro_cp/cp240"
I get returned "ERROR 400 - Bad Request - your browser sent a message
the server could not understand"

I use exactly the same method to perform the call.
remove the http:
connect to the socket on "epp.eurostat.cec.eu.int"
and perform my http on
"/portal/page?_pageid=1996,39140985&_dad=portal&_schema=PORTAL&screen=detailref&language=en&product=EUROIND&root=EUROIND/shorties/euro_cp/cp240"

I assume all the ? and , are some sort of parameter list, and i can
find no documentation to help me understand this.
If anyone could help me or know when to find the relevant information
from i would be most grateful
cheers
Anthony

Please post to 'comp.infosystems.www.authoring.cgi'. Your question has
nothing to do with C++ language and as such is off-topic here.

I don't know that newsgroup, but it sounds like the wrong one, too. This has
nothing to do with CGI. It's about the http protocol. One probably good
source of information about that protocol might be the RFC that defines it.
To the OP: See http://www.faqs.org/rfcs/rfc2616.html

Did you do what I suggested last time you asked?

Please be more careful with quoting. I wasn't the one who wrote that.

They will only if the OP is using Windows. Otherwise, they will be
completely useless to him.
