Browser for iphone with no timeout

I'm looking for a 3rd-party browser that gives my intranet webpage as long as 2 minutes to respond. I have been unsuccessful so far, and I've tried at least 4 different browsers. Safari has a 60-second timeout that is not adjustable from what I can see.

Google and searches on this forum have turned up nothing, so this post is my last ditch effort to find a browser I can use with an intranet webpage that takes up to 2 minutes to get back to the browswer after a request has been made.

Anyone know of one?

 

Unfortunately these are company-issued iPhones and cannot be messed with/jailbroken. We're dealing with around 3 dozen iPhones. It's too bad the execs who decided to switch from Blackberry to iPhone didn't consult us IT weenies first to make sure the critical apps would still work.
