-

i have been setting mvc project webapi. have working not know why calls have additional pieces url's.

example:

/api/user/zholen?_=1373490280823

can explain me number @ end for? seems attached calls , ones call via javascript.

i using amplify.js when making these calls javascript. noticed number increments per call ***23, 24, 25 etc.

i send cookie each call stores information current logged on user.

i not sure which, if any, of these things causing number generated.

jquery adds ajax urls prevent caching.

to prevent this, pass cache: true option.
