This [[Module Library|XQuery Module]] contains a single function to send HTTP requests and handle HTTP responses. The function {{Code|send-request}} is based on the [http://expath.org/spec/http-client EXPath HTTP Client Module]. It gives full control over the available request and response parameters. For simple GET requests, the [[Fetch Module]] may be sufficient.
If <code><http:header name="Accept-Encoding" value="gzip"/></code> is specified and if the addressed web server provides support for the {{Code|gzip}} compression algorithm, the response will automatically be decompressed.

| '''Summary'''
|Sends an HTTP request and interprets the corresponding response. :* {{Code|$request}} contains the parameters of the HTTP request such as HTTP method and headers. * In addition to this it can also contain the URI to which the request will be sent and the body of the HTTP method. * If the URI is not given with the parameter {{Code|$href}}, its value in {{Code|$request}} is used instead.<br/>* The structure request body can also be supplied via the {{Code|$bodies}} parameter. Notes:* Both basic and digest authentication is supported.* While the contents of the request can be supplied as child of the {{Code|http:requestbody}} element follows , it is faster and safer to pass them on via the third argument.* For further information, please check out the [http://expath.org/spec/http-client EXPath] specification. Both basic and digest authentication is supported.
