removeProductsNotVisited ( int _securityFrequency ) : string
In PricesTracker only.
It removes products which are not visited on the competitor (only in a complete analysis).
There is a security in the function so that it does not trigger for example if the site is under maintenance. The function is bypassed if less than 40 Urls have been crawled.
Parameters
_securityFrequency (optional)
During crawling, several events can occur, making this function dangerous. Some pages may not be found, or the server may block or saturate them. Thus, between 2 crawlings, the pages crawled may vary. This parameter will accumulate data over a defined number of crawls. For example, if _securityFrequency = 5, nothing will happen during the first 4 crawls whose links will be memorized. Then, on the 5th crawl, a table containing all the links found during the 5 crawls will be used to delete the missing products.
