I'm using idol http connector to indexing our intranet website,
and adding one fetch job in the spider.

when crawling for the targeting website, have the following issue,

Error when executing a request: Connection was closed before the whole entity has been read/written

Anyone can show me the way to get rid of this kind of error and Retrying URL?
