Etag is +usually part of headers returned by a request. When server sends an +ETag, it must be enveloped by a double quote. This option extracts the +ETag without the double quotes and saves it into the <file>. + +A server can send a week ETag which is prefixed by "W/". This identifier +is not considered, and only relevant ETag between quotation marks is parsed. + +It an ETag wasn't send by the server or it cannot be parsed, and empty +file is created. |
