void xmlNanoHTTPInit (void);
Initialize the HTTP protocol layer. Currently it just checks for proxy informations
void 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 |
int xmlNanoHTTPFetch (const char *URL, const char *filename, char **contentType);

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 |
void* xmlNanoHTTPMethod (const char *URL, const char *method, const char *input, char **contentType, const char *headers, int ilen);

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 |
void* 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 |
void* 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 |
void* 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 |
int xmlNanoHTTPReturnCode (void *ctx);
Get the latest HTTP return code received
ctx: | the HTTP context |
Returns : | the HTTP return code for the request. |
const 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. |
const char* xmlNanoHTTPRedir (void *ctx);
Provides the specified redirection URL if available from the HTTP header.
Return the specified redirection URL or NULL if not redirected.
ctx: | the HTTP context |
Returns : |

const char* xmlNanoHTTPMimeType (void *ctx);
Provides the specified Mime-Type if specified in the HTTP headers.
Return the specified Mime-Type or NULL if not available
ctx: | the HTTP context |
Returns : |
int 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. |
int xmlNanoHTTPSave (void *ctxt, const char *filename);
