This consists of three parts: 1. If the URL looks suspiciously like an archive, send a HEAD first to check the Content-Type is HTML, to avoid downloading a large file. Raise `_NotHTTP` if the content type cannot be determined, or `_NotHTML` if it is not HTML. 2. Actually perform the request. Raise HTTP exceptions on network failures. 3. Check the Content-Type header to make sure we got HTML, and raise `_NotHTML` otherwise. �r? zGetting page %sr8 z max-age=0)�Acceptz Cache-Control)r9 ) r r �filenamerL �logger�debugr r: r r= )r r? rK r$ r$ r% �_get_html_response` s ��rR )r9 r c C s2 | r.d| v r.t �| d �\}}d|v r.|d S dS )z=Determine if we have any encoding information in our headers.r6 �charsetN)�cgi� parse_header)r9 r( �paramsr$ r$ r% �_get_encoding_from_headers� s rW )�document�page_urlr c C s. | � d�D ] }|�d�}|dur | S q |S )a� Determine the HTML document's base URL.
