Visual Basic 6 prototype which can reliably download over 50 web pages asynchronously -- PROFESSIONALS ONLY

Hello to all,

Before I begin I must warn you that the process of selection will be thorough, and this is why: I have found various ways of accomplishing the task but I need the best one in performance, speed, reliabilty and sturdiness. I intend on stressing out the software very much.

I need to download (asynchronously) many internet (http) web pages and then parse the information.

when searching I need to be able to monitor the downloading progress of the page (and the entire process of the thread). I need to know in seconds how long it took to download and any other information about the transaction (headers, referers, cookie, etc..)

The program must be in Visual Basic 6 and I prefer not using any components. I know there are ways to use windows Sockets or other stuff.... I am open to suggestions but the winner will be the one who can suggest and create the fastest and most detailes prototype.I will be judging the prototype on:

1) reliability (always downloading the page succesfully )

2) sturdiness (50+ urls to download at the same time (asynchronously))

3) easy ntegration on windows machines (using core window components rather than vb6 or 3rd party components.)

As for parsing, I just need a good parsing technology, I would simply need a demonstartion, it would not be required (unless you want to and we can arrange something then) to parse every url I supply to you.

Keep in mind I need to use Referer's, cookies, GET, POST and HTTP, HTTPS.

There are some trade secrets (url's for instance), So I will ask for a NDA before accepting the bid.

Please ONLY PROFESSIONALS APPLY, I am no beginner and am not looking for a small solution. Thank you for your time, should you need more specific information, I will gladly give it.

Best Regards,
