# Method Protocols.HTTP.put_url()

Method put_url

  `.Query put_url(string|Standards.URI url, void|string file, 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 PUT 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.
