i have a preety old site almost 6 yrs old and good traffic and pr. since so many days i am seeing some entries in my awstats 404 entries like my-valid-url1.html!RSTB_ERROR_NCURL_IGNORE_ALL
my-valid-url2.html!RSTB_ERROR_NCURL_IGNORE_ALL
my-valid-url3.html!RSTB_ERROR_NCURL_IGNORE_ALL
my-valid-url4.html!RSTB_ERROR_NCURL_IGNORE_ALL
Apart of this my awstats 404 entries are also showing huge number of urls as 404 which were never been there in the site.
myfolder/mypage.html - valid url
myfolder/myotherfolder/myotherfolder/mypage.html - invalid url - caught in 404 entries
I am surprized how come ppl reached to those urls which are not available in the site and never been there online or offline.
is it the user egenrated entries or a scraper cud be the reason
