HTTP Access
Hi there,
I'm writing some software which in many ways is like a Browser (Netscape, Internet Explorer and co.).
It retrieves HTML pages from HTTP servers.
Mostly it works just fine, yet there are a number of sites that elude me.
Such sites are:
http://www.applelinks.com
http://www.expectingrain.com
When I access these sites from std. browsers, such as those I've mentioned, things work fine.
Yet when my software accesses them, I don't get the same HTML content these browsers get.
More info:
1. I use the std. HTTP 1.0 method of GET (and it works fine in 99% of the cases
2. I tested this on the Internet Sample PowerPlant provides, with the same results.
3. If you try these sites with the Internet Sample, you'll note Expecting Rain returns the HTTP Location header information. I honor that, but still don't get the info. std. browsers get.
The question:
What extra information do Netscape/IE send (and I should send) in order to get the correct HTML info back from these sites?
Thanks,
Roov

The obvious problem showed it's face immediatly: some sites do not send you back all requested data if you don't specify the (optional) "Host" field in the HTTP request header.
Once I realized that, things worked fine...
