http:hostname[:port][/resourceUri][?param1=value1][&param2=value2]

You can only produce to endpoints generated by the HTTP component. Therefore it should never be used as input into your camel Routes. To bind/expose an HTTP endpoint via a HTTP server as input to a camel route, you can use the Jetty Component or the Servlet Component

{div:class=confluenceTableSmall}
|| Name || Default Value || Description ||
| {{throwExceptionOnFailure}} | {{true}} | Option to disable throwing the {{HttpOperationFailedException}} in case of failed responses from the remote server. This allows you to get all responses regardless of the HTTP status code. |
| {{bridgeEndpoint}} | {{false}} | If the option is true , HttpProducer will ignore the Exchange.HTTP_URI header, and use the endpoint's URI for request. You may also set the * throwExceptionOnFailure* to be false to let the HttpProducer send all the fault response back. \\
*Camel 2.3:* If the option is true, HttpProducer and CamelServlet will skip the gzip processing if the content-encoding is "gzip". |
| {{disableStreamCache}} | {{false}} | DefaultHttpBinding will copy the request input stream into a stream cache and put it into message body if this option is false to support read it twice, otherwise DefaultHttpBinding will set the request input stream direct into the message body. |
| {{httpBindingRef}} | {{null}} | *Deprecated and will be removed in Camel 3.0:* Reference to a {{org.apache.camel.component.http.HttpBinding}} in the [Registry]. Use the {{httpBinding}} option instead. |
| {{httpBinding}} | {{null}} | *Camel 2.3:* Reference to a {{org.apache.camel.component.http.HttpBinding}} in the [Registry]. |
| {{httpClientConfigurerRef}} | {{null}} | *Deprecated and will be removed in Camel 3.0:* Reference to a {{org.apache.camel.component.http.HttpClientConfigurer}} in the [Registry]. Use the {{httpClientConfigurer}} option instead. |
| {{httpClientConfigurer}} | {{null}} | *Camel 2.3:* Reference to a {{org.apache.camel.component.http.HttpClientConfigurer}} in the [Registry]. |
| {{httpClient.XXX}} | {{null}} | Setting options on the [HttpClientParams|http://hc.apache.org/httpclient-3.x/apidocs/org/apache/commons/httpclient/params/HttpClientParams.html]. For instance {{httpClient.soTimeout=5000}} will set the {{SO_TIMEOUT}} to 5 seconds. |
| {{clientConnectionManager}} | {{null}} | To use a custom {{org.apache.http.conn.ClientConnectionManager}}. |
| {{transferException}} | {{false}} | *Camel 2.6:* If enabled and an [Exchange] failed processing on the consumer side, and if the caused {{Exception}} was send back serialized in the response as a {{application/x-java-serialized-object}} content type (for example using [Jetty] or [Servlet] Camel components). On the producer side the exception will be deserialized and thrown as is, instead of the {{HttpOperationFailedException}}. The caused exception is required to be serialized. |
| {{headerFilterStrategy}} | {{null}} | *Camel 2.11:* Reference to a instance of {{org.apache.camel.spi.HeaderFilterStrategy}} in the [Registry]. It will be used to apply the custom headerFilterStrategy on the new create HttpEndpoint. |
| {{urlRewrite}} | {{null}} | *Camel 2.11:* *Producer only* Refers to a custom {{org.apache.camel.component.http.UrlRewrite}} which allows you to rewrite urls when you bridge/proxy endpoints. See more details at [UrlRewrite] and [How to use Camel as a HTTP proxy between a client and server]. |

{div:class=confluenceTableSmall}
|| Name || Default Value || Description ||
| {{authMethod}} | {{null}} | Authentication method, either as {{Basic}}, {{Digest}} or {{NTLM}}. |
| {{authMethodPriority}} | {{null}} | Priority of authentication methods. Is a list separated with comma. For example: {{Basic,Digest}} to exclude {{NTLM}}. |
| {{authUsername}} | {{null}} | Username for authentication |
| {{authPassword}} | {{null}} | Password for authentication |
| {{authDomain}} | {{null}} | Domain for NTML authentication |
| {{authHost}} | {{null}} | Optional host for NTML authentication |
| {{proxyHost}} | {{null}} | The proxy host name |

| {{Exchange.HTTP_PATH}} | {{String}} | Request URI's path, the header will be used to build the request URI with the HTTP_URI. *Camel 2.3.0:* If the path is start with "/", http producer will try to find the relative path based on the Exchange.HTTP_BASE_URI header or the exchange.getFromEndpoint().getEndpointUri(); |
| {{Exchange.HTTP_QUERY}} | {{String}} | URI parameters. Will override existing URI parameters set directly on the endpoint. |
| {{Exchange.HTTP_RESPONSE_CODE}} | {{int}} | The HTTP response code from the external server. Is 200 for OK. |
| {{Exchange.HTTP_CHARACTER_ENCODING}} | {{String}} | Character encoding. |
| {{Exchange.CONTENT_TYPE}} | {{String}} | The HTTP content type. Is set on both the IN and OUT message to provide a content type, such as {{text/html}}. |
| {{Exchange.CONTENT_ENCODING}} | {{String}} | The HTTP content encoding. Is set on both the IN and OUT message to provide a content encoding, such as {{gzip}}. |
| {{Exchange.HTTP_SERVLET_REQUEST}} | {{HttpServletRequest}} | The {{HttpServletRequest}} object. |
| {{Exchange.HTTP_SERVLET_RESPONSE}} | {{HttpServletResponse}} | The {{HttpServletResponse}} object. |
| {{Exchange.HTTP_PROTOCOL_VERSION}} | {{String}} | *Camel 2.5:* You can set the http protocol version with this header, eg. "HTTP/1.0". If you didn't specify the header, HttpProducer will use the default value "HTTP/1.1" |
