Fetches data from an HTTP or HTTPS URL and writes the data to the content of a FlowFile. Once the content has been fetched, the ETag and Last Modified dates are remembered (if the web server supports these concepts). This allows the Processor to fetch new data only if the remote data has changed or until the state is cleared. That is, once the content has been fetched from the given URL, it will not be fetched again until the content on the remote server changes. Note that due to limitations on state management, stored “last modified” and etag fields never expire. If the URL in GetHttp uses Expression Language that is unbounded, there is the potential for Out of Memory Errors to occur.

In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, whether a property supports the Expression Language Guide, and whether a property is considered “sensitive”, meaning that its value will be encrypted. Before entering a value in a sensitive property, ensure that the file has an entry for the property nifi.sensitive.props.key.
