Hi

I am doing a small screen scraping project and the requirement is to
scrape a website which shows search results.

I am able to scrape the results of the first search page successfully
but since search results are in paging, ( divided into many pages ) I
am unable to send a second request with page number within my first
HTTPweb request.

I am a bit new to this type of work.
Can anyone tell me how this can be achieved, How can I scrape all
search results in all pages.

Regards
Chris
 
Usually, there is a link to further results, and more often than not, it
contains a query string that identifies which "page" it is linking to. If
you can identify the link, you can use it to request each successive "page"
of results.

Hi Kevin,

I am able to identify the link and calling the second page also, but
somehow not getting the response. The next page always gives response
as no search results available. However when I do it manually there
are results.

So I assume somehow session or some other state persistence drops in
between first and second request.

Thanks
Chris
 
The Session ID will be in a non-persistent cookie passed back to the
original page.
