IPad – Clearing local storage in safari on iPad

I just could use Crop multiple pages in a pdf file method to remove the bleed marks. I cropped the original pdf book by making the cropping area the same as the page that is shown.

After the cropping the file size became 6.1MB from 3.8MB, but it didn't matter to me.

If the main idea is scripting Safari, I would try using Automator before trying AppleScript. I'd start by hitting the record button and then:

• Open Safari
• Navigate to your webpage
• GET by saving the webpage source
• Allow the page to do whataver AJAX calls you may want it to do
  • save the webpage source again
• Fill out a form, hit submit for your POST
  • save the webpage source yet again

Or you could try AppleScript with something like this:

tell application "Safari"
    tell window 1
    set current tab to (make new tab with properties {URL:"http://www.example.com"})
    end tell
end tell

You can add to the script form fills and submit buttons with javascript:

do JavaScript "document.getElementById('field').value = '" & myvalue & "'"
do JavaScript "document.forms[\"form\"].submit();"

I'd try this out within the JavaScript console within a web browser first to make sure you have the names of everything correct.
