I crwaled two of my sites, once using the scipt installed at my server and once by your online script at www.xml-sitemaps.com
Your free script : crawled 435 url
My script : crawled 98 url only and gave completed message
second site :
your free script: crawled 431
My script : crawled 484 url
while in a third site it stops after crawling 2000 url, so I had to split crawling to crawl all my site.
Do yo have an explanation for this matter.
