# Method Protocols.HTTP.delete_url()

Method delete_url

  ``.Query` delete_url(`string`|`Standards.URI` `url`, `void`|`mapping`(`string`:`int`|`string`|`array`(`string`)) `query_variables`, `void`|`mapping`(`string`:`string`|`array`(`string`)) `request_headers`, `void`|`Protocols.HTTP.Query` `con`)`

Description

  Sends a HTTP DELETE request to the server in the URL and returns the created and initialized Query object. `0` is returned upon failure. If a query object having `request_headers->Connection=="Keep-Alive"` from a previous request is provided and the already established server connection can be used for the next request, you may gain some performance.
