• Problem with modifying a page with ajax, and the browser keeping the unmodified page in cache.

  - by David Lawson

  Hey there, I have a situation where my page loads some information from a database, which is then modified through AJAX. I click a link to another page, then use the 'back' button to return to the original page. The changes to the page through AJAX I made before don't appear, because the browser has the unchanged page stored in the cache. Is there a way of fixing this without setting the page not to cache at all? Thanks :)

Is there a setting that handles this?

Is it truly supported?

• Out of browser silverlight 4 application with local database that will run and install on windows or

  - by user360894

  I am researching using silverlight 4 to develop a desktop application that can be installed from a browser window, now the tricky part is that I want a lightweight database embedded into the application. The database should install with the rest of the application and it should ideally work on both windows and mac systems. Originally I was thinking sqlite would be suitable for this but I have learned that it is not compatible with silverlight. Does anyone know of a solution for this?

• how to detect an F5 refresh keypress event in jquery?

  - by chaonextdoor

  I noticed that jquery has a keypress function. But it seems that it can only detect keypress event of numbers and characters. It cannot detect the F5 keypress event. And What surprises me the most is everyone online says that the keyCode of F5 is 116, But when I use the jquery keypress function, it just shows that the character t has the keyCode of 116(it seems that 116 is the ascii code of lowercase t)! Can somebody give me any idea about this and how to detect the F5 event in javascript or jquery? Thanks so much in advance.
