Any possibilty of making this?

[dr.adro]

I have one big question, since i have few/several sites with more then a million pages up to 3 million pages, i would like to somehow gather site structure or analyze it before i even start crawl, so i could exclude things etc...

or maybe perhaps this thingy:

"1 out of every ---" taking an integer from 1 to 100

example: "10"
so if 1 out of 10
scans 1
skips 9

would cut 250k into 25k pages to scan

If you have any ideas i would love to hear them...

Hello,

you can set the "Maximum number of URLs" option to make an initial limited scan and then check created sitemaps to see the URLs list.
