Url has ?_=*Number* after each GET call?

I have been setting up a mvc project with a webapi. I have it working but I do not know why my GET calls have additional pieces to their URL's.

Example:

/api/User/Zholen?_=1373490280823

Can someone explain to me what this number at the end is for? It seems to only be attached to GET calls and only the ones I personally call via javascript.

I am using amplify.js when making these calls from javascript. I noticed that the number increments per call ***23, 24, 25 etc.

I do also send a cookie with each call which stores information about the current logged on user.

I am not sure which, if any, of these things are causing this number to be generated.

Solution

  • jQuery adds this to AJAX URLs to prevent caching.

    To prevent this, pass cache: true as an option.
