Hi!
There is some problem that i am facing with ajax calls. In some systems all calls are getting fired as required. However in some systems the same code is failing. However if from those systems where it is failing - i go and do Tools --> Internet Options --> Delete Cookies --> Delete Files then the call ajax call is working fine.

I am going nuts trying to fix this issue.

Any help ... i'll give you a treat

Sounds like you are cached. Are you setting no cache headers for content that is not supposed to be cached?

Yes, I have the following code for the cache.

response.setHeader("Expires", "Sat, 6 May 1995 12:00:00 GMT");
// Set standard HTTP/1.1 no-cache headers.
response.setHeader("Cache-Control","no-store, no-cache, must-revalidate");
// Set IE extended HTTP/1.1 no-cache headers (use addHeader).
response.addHeader("Cache-Control", "post-check=0, pre-check=0");
// Set standard HTTP/1.0 no-cache header.
response.setHeader("Pragma", "no-cache");


Is it that this code is wrong?

Regards,

Rohit

Hello,

I have got the solution to this. I think its because of a browser cache issue. What we need to do is as follows:



So this will append a new timestanp each and every time you invoke it thus creating a new url.

The If Modified since is a better solution that the random query string. Both work, the modified header is cleaner.
