 void	xmlNanoHTTPScanProxy		(const char * URL) DescriptionFunction: xmlNanoHTTPAuthHeaderconst char *	xmlNanoHTTPAuthHeader	(void * ctx)
 Get the authentication header of an HTTP context | ctx: | the HTTP context |  | Returns: | the stashed value of the WWW-Authenticate or Proxy-Authenticate header. | 
Function: xmlNanoHTTPCleanupvoid	xmlNanoHTTPCleanup		(void)
 Cleanup the HTTP protocol layer. Function: xmlNanoHTTPClosevoid	xmlNanoHTTPClose		(void * ctx)
 This function closes an HTTP context, it ends up the connection and free all data related to it. Function: xmlNanoHTTPContentLengthint	xmlNanoHTTPContentLength	(void * ctx)
 Provides the specified content length from the HTTP header. | ctx: | the HTTP context |  | Returns: | the specified content length from the HTTP header. Note that a value of -1 indicates that the content length element was not included in the response header. | 
Function: xmlNanoHTTPEncodingconst char *	xmlNanoHTTPEncoding	(void * ctx)
 Provides the specified encoding if specified in the HTTP headers. | ctx: | the HTTP context |  | Returns: | the specified encoding or NULL if not available | 
Function: xmlNanoHTTPFetchint	xmlNanoHTTPFetch		(const char * URL, const char * filename,
 char ** contentType)
 
 This function try to fetch the indicated resource via HTTP GET and save it's content in the file. | URL: | The URL to load |  | filename: | the filename where the content should be saved |  | contentType: | if available the Content-Type information will be returned at that location |  | Returns: | -1 in case of failure, 0 incase of success. The contentType, if provided must be freed by the caller | 
Function: xmlNanoHTTPInitvoid	xmlNanoHTTPInit			(void)
 Initialize the HTTP protocol layer. Currently it just checks for proxy informations Function: xmlNanoHTTPMethodvoid *	xmlNanoHTTPMethod		(const char * URL, const char * method,
 const char * input,
 char ** contentType,
 const char * headers,
 int ilen)
 
 This function try to open a connection to the indicated resource via HTTP using the given @method, adding the given extra headers and the input buffer for the request content. | URL: | The URL to load |  | method: | the HTTP method to use |  | input: | the input string if any |  | contentType: | the Content-Type information IN and OUT |  | headers: | the extra headers |  | ilen: | input length |  | Returns: | NULL in case of failure, otherwise a request handler. The contentType, if provided must be freed by the caller | 
Function: xmlNanoHTTPMethodRedirvoid *	xmlNanoHTTPMethodRedir		(const char * URL, const char * method,
 const char * input,
 char ** contentType,
 char ** redir,
 const char * headers,
 int ilen)
 
 This function try to open a connection to the indicated resource via HTTP using the given @method, adding the given extra headers and the input buffer for the request content. | URL: | The URL to load |  | method: | the HTTP method to use |  | input: | the input string if any |  | contentType: | the Content-Type information IN and OUT |  | redir: | the redirected URL OUT |  | headers: | the extra headers |  | ilen: | input length |  | Returns: | NULL in case of failure, otherwise a request handler. The contentType, or redir, if provided must be freed by the caller | 
Function: xmlNanoHTTPMimeTypeconst char *	xmlNanoHTTPMimeType	(void * ctx)
 Provides the specified Mime-Type if specified in the HTTP headers. | ctx: | the HTTP context |  | Returns: | the specified Mime-Type or NULL if not available | 
Function: xmlNanoHTTPOpenvoid *	xmlNanoHTTPOpen			(const char * URL, char ** contentType)
 
 This function try to open a connection to the indicated resource via HTTP GET. | URL: | The URL to load |  | contentType: | if available the Content-Type information will be returned at that location |  | Returns: | NULL in case of failure, otherwise a request handler. The contentType, if provided must be freed by the caller | 
Function: xmlNanoHTTPOpenRedirvoid *	xmlNanoHTTPOpenRedir		(const char * URL, char ** contentType,
 char ** redir)
 
 This function try to open a connection to the indicated resource via HTTP GET. | URL: | The URL to load |  | contentType: | if available the Content-Type information will be returned at that location |  | redir: | if available the redirected URL will be returned |  | Returns: | NULL in case of failure, otherwise a request handler. The contentType, if provided must be freed by the caller | 
Function: xmlNanoHTTPReadint	xmlNanoHTTPRead			(void * ctx, void * dest,
 int len)
 
 This function tries to read @len bytes from the existing HTTP connection and saves them in @dest. This is a blocking call. | ctx: | the HTTP context |  | dest: | a buffer |  | len: | the buffer length |  | Returns: | the number of byte read. 0 is an indication of an end of connection. -1 indicates a parameter error. | 
Function: xmlNanoHTTPRedirconst char *	xmlNanoHTTPRedir	(void * ctx)
 Provides the specified redirection URL if available from the HTTP header. | ctx: | the HTTP context |  | Returns: | the specified redirection URL or NULL if not redirected. | 
Function: xmlNanoHTTPReturnCodeint	xmlNanoHTTPReturnCode		(void * ctx)
 Get the latest HTTP return code received | ctx: | the HTTP context |  | Returns: | the HTTP return code for the request. | 
Function: xmlNanoHTTPSaveint	xmlNanoHTTPSave			(void * ctxt, const char * filename)
 
 This function saves the output of the HTTP transaction to a file It closes and free the context at the end | ctxt: | the HTTP context |  | filename: | the filename where the content should be saved |  | Returns: | -1 in case of failure, 0 incase of success. | 
Function: xmlNanoHTTPScanProxyvoid	xmlNanoHTTPScanProxy		(const char * URL)
 (Re)Initialize the HTTP Proxy context by parsing the URL and finding the protocol host port it indicates. Should be like http://myproxy/ or http://myproxy:3128/ A NULL URL cleans up proxy informations. | URL: | The proxy URL used to initialize the proxy context |
