I don't care in which language it's coded, as long as it works and does what I want. It could even be in Auto It. Although I prefer VB.Net since I know a little something. I basically need a web browser but with some special features. Features needed: Auto rotate a list of Useragents in a TXT file on every time I hit a website Weight to each Useragent. For IE: Iexplorer 6.0 xxxxx - 10 / Firefox mozilla xxxxx 5 . So Explorer will be used 2 times more than Firefox, etc. Multitabs for multiple browsing. Autosurf on each tab with timer. For IE: each 20 seconds, rotate from a list of urls. Proxy support for EACH tab, so I can use different proxies for each tab. LOW memory use. I don't want a memory hog when running 20 tabs. Referrer rotation with weight, from a txt file. I think that's about it. I have some other features I would need but PM if you are interested so I can tell you what it's about. I don't want to disclose my whole project here. If you're interested, PM me your price for the application, price for the source code and estimated delivery time. Thank you.
