Safari Failing to Open Web Pages

Hello,

I own an iPhone 5c running iOS 8.3.

I noticed a while ago that when browsing the internet with Safari, many of the websites I tried to visit would fail to load with a message saying too many redirects.

I found that if I allowed cookies this would resolve that issue (Although I'd rather not allow cookies).

Even if I allow cookies though, some websites fail to load with a message saying "Safari cannot open the page because it could not load any data." In order for me to get around this I have to close the tab, open a new tab and then open the website again.

What is problem here? Why am I being forced to allow cookies in order to prevent Safari from failing to open a site and why am I having to open a new tab to navigate to webpages?

This is an issue that has come out of the blue after a long while of internet browsing without me ever changing any settings.

Hope someone can shed some light on this matter.

Thanks!
