The Request screen provides the following settings:
Use this control to customize the way SiteSucker identifies itself when making a request. Some sites are very particular about which browsers they will allow. You can you use this feature to "fool" the site into thinking that you are using an approved browser.
To change SiteSucker's identity, simply tap on this control and select one of the Web browsers listed. (If you choose None, SiteSucker will not include any identifying information when making requests.)
Use this control to specify the number of times SiteSucker should attempt to download a file. SiteSucker will only retry downloading a file if a timeout, network connection, or too many requests (429) error occurs.
Use this control to select the length of time that SiteSucker should wait for a response from the server.
Use this control to specify the length of time that SiteSucker should delay between download requests. This feature allows SiteSucker to use less bandwidth and avoid anti-mining safeguards employed by some sites.
If a Crawl-delay is already being imposed by the site's robots.txt file, the longer of the two delays will be used. See Robot Exclusions for more information about the robots.txt file.
