Stop safari from refreshing every page i go back to

Question

Is there a way to prevent safari from refreshing every page i go back to in my browsing history?  what is the point of having a cache if safari is going to refresh every page anyway?
i dont mean dated stuff like 2 weeks ago, i mean every page.
i swipe and have to wait while safari refreshes, then swipe back again, wait for the refresh and repeat this.  if i quickly swipe back 4 pages, the 4th page back will appear for a second, then the 1st page re-appears cos it is fully refreshed.
i thought it was just on Facebook that this happened on, but it is on most pages including google searches and this forum.
very annoying behaviour.

Answer 1

I am part of a web marketing company and we discovered a very heavy aggravation on top of all the above described annoyances of the refreshing process of safari on iPhone and iPad.
If the page in refreshing process it was after a direct click on a google "pay per click add", then safari it would re-emulate the click on the google add as well, who will charge the customer for what it looks like a legitimate click !!!!!
Now my customer put me in charge to collect all the company server's logs and analyse them through one by one ... (millions…),
once sufficient data will be available we will start a suing process against apple and google.
Apple, to allow such automatic unconditioned refreshing generating false "pay per click", and Google for charging the customer for illegal clicks. Keep in mind that we receive from 500 to 600 clicks per day at a CPC min £1.90 to max £6.80 depends from competitors biddings, the highest percentage of clicks its about CPC £3.10, making the company spending easily £3,000 per day.
in the last 7 days we already discovered that about 10% of the clicks are repetitive from iPhone and iPad refreshing their safari cache, making spend the company about £ 2,000 per week in false clicks. we are also trying to discover when was this process generally started,  ie if its been going on for a year, we are talking of some good (£2000 * 52) £100,000 plus our work to investigate.
I am a big fan of iPhone, and I hope some apple technician will read this message and take action ASAP, because in the next 3-4 weeks, once our investigation its done, all the info and server logs will be publicised on the web … with unfortunate financial consequences …
