Hi!
I am trying to write a client for pretty... well... creatively 
designed web API. The server gives HTTP status 500 replies if 
the requests are malformed, but the actual error message is 
hidden in the body of the reply (an XML document!). 
std.net.curl.get() throws an exception in this case. But I 
would like to get the body to process the error message within. 
How can I do that?

Thanks in advance,

It seems you can't, that simple get wrapper is very limited.
Better create you own get function, example:

import std;

ushort get(string url, ref ubyte[] content)
{
    auto cont = appender(&content);
    auto http = HTTP();
    http.method = HTTP.Method.get;
    http.url = url;
    http.onReceive = (ubyte[] data)
    {
        cont ~= data;
        return data.length;
    };
    HTTP.StatusLine status;
    http.onReceiveStatusLine = (HTTP.StatusLine s) { status = s; 
};
    http.perform();
    return status.code;
}

void main()
{
    ubyte[] data;
    auto scode = get("http://dlang.org/asdf";, data);
    if (scode == 404)
    {
    // data has the body
    ...
}
