Checks the host v component for RFC2396 compliance and against the URI::Parser Regexp for :HOST.
Can not have a registry or opaque component defined, with a host component defined.
Returns a proxy URI. The proxy URI is obtained from environment variables such as http_proxy, ftp_proxy, no_proxy, etc. If there is no proper proxy, nil is returned.
If the optional parameter env is specified, it is used instead of ENV.
Note that capitalized variables (HTTP_PROXY, FTP_PROXY, NO_PROXY, etc.) are examined, too.
But http_proxy and HTTP_PROXY is treated specially under CGI environment. It’s because HTTP_PROXY may be set by Proxy: header. So HTTP_PROXY is not used. http_proxy is not used too if the variable is case insensitive. CGI_HTTP_PROXY can be used instead.

Adds server as a virtual host.
Creates the HTTPRequest used when handling the HTTP request. Can be overridden by subclasses.
Returns the bytes to be read again when Encoding::InvalidByteSequenceError occurs.
possible opt elements:
hash form: :partial_input => true # source buffer may be part of larger source :after_output => true # stop conversion after output before input integer form: Encoding::Converter::PARTIAL_INPUT Encoding::Converter::AFTER_OUTPUT
possible results:
:invalid_byte_sequence :incomplete_input :undefined_conversion :after_output :destination_buffer_full :source_buffer_empty :finished
primitive_convert converts source_buffer into destination_buffer.
source_buffer should be a string or nil. nil means an empty string.
destination_buffer should be a string.
destination_byteoffset should be an integer or nil. nil means the end of destination_buffer. If it is omitted, nil is assumed.
destination_bytesize should be an integer or nil. nil means unlimited. If it is omitted, nil is assumed.
opt should be nil, a hash or an integer. nil means no flags. If it is omitted, nil is assumed.
primitive_convert converts the content of source_buffer from beginning and store the result into destination_buffer.
destination_byteoffset and destination_bytesize specify the region which the converted result is stored. destination_byteoffset specifies the start position in destination_buffer in bytes. If destination_byteoffset is nil, destination_buffer.bytesize is used for appending the result. destination_bytesize specifies maximum number of bytes. If destination_bytesize is nil, destination size is unlimited. After conversion, destination_buffer is resized to destination_byteoffset + actually produced number of bytes. Also destination_buffer’s encoding is set to destination_encoding.
primitive_convert drops the converted part of source_buffer. the dropped part is converted in destination_buffer or buffered in Encoding::Converter object.
primitive_convert stops conversion when one of following condition met.
invalid byte sequence found in source buffer (:invalid_byte_sequence) primitive_errinfo and last_error methods returns the detail of the error.
unexpected end of source buffer (:incomplete_input) this occur only when :partial_input is not specified. primitive_errinfo and last_error methods returns the detail of the error.
character not representable in output encoding (:undefined_conversion) primitive_errinfo and last_error methods returns the detail of the error.
after some output is generated, before input is done (:after_output) this occur only when :after_output is specified.
destination buffer is full (:destination_buffer_full) this occur only when destination_bytesize is non-nil.
source buffer is empty (:source_buffer_empty) this occur only when :partial_input is specified.
conversion is finished (:finished)
example:
ec = Encoding::Converter.new("UTF-8", "UTF-16BE") ret = ec.primitive_convert(src="pi", dst="", nil, 100) p [ret, src, dst] #=> [:finished, "", "\x00p\x00i"] ec = Encoding::Converter.new("UTF-8", "UTF-16BE") ret = ec.primitive_convert(src="pi", dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "i", "\x00"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "", "p"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "", "\x00"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:finished, "", "i"]
Inserts string into the encoding converter. The string will be converted to the destination encoding and output on later conversions.
If the destination encoding is stateful, string is converted according to the state and the state is updated.
This method should be used only when a conversion error occurs.
