| 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 |

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 |

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 | 
| void*       xmlNanoHTTPOpen                 (const char *URL,

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 | 
| int xmlNanoHTTPReturnCode (void *ctx); | 
| ctx : | the HTTP context | 
| Returns : | the HTTP return code for the request. | 
| int         xmlNanoHTTPRead                 (void *ctx,

                                             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. |

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. |
