Login Problem with IE/Edge (caching issue?) #4823

bomaint created 6 years ago

Hello,

I am experiencing a strange error when trying to log in with IE/Edge, in the UI nothing happens and when I look at the console I see a "Unexpected authenticateResult!". I put a breakpoint in "login.service.ts" inside the subscribe function of the authenticate call:

this._tokenAuthService
    .authenticate(this.authenticateModel)
    .finally(finallyCallback)
    .subscribe((result: AuthenticateResultModel) => {
    ->    this.processAuthenticateResult(result, redirectUrl);
    });

In Chrome the result is populated but in IE/Edge the result is empty (all properties are undefined). What I also saw is that in IE/Edge I see an additional GET call to <a class="postlink" href="http://localhost:22742/api/TokenAuth/Authenticate">http://localhost:22742/api/TokenAuth/Authenticate</a> with remark "(from cache)". Looking at the timings it seems as if the GET (cache) call is fired at exactly the same time as the POST call and finishes (of course if it's really from cache) before the POST returns. This would explain why the result is empty if it is taken from some unknown cached result. I checked the headers and all the headers that should prevent caching have been applied:

Accept: application/json
Accept-Encoding: gzip, deflate
Accept-Language: en-CH, en; q=0.5
Cache-Control: no-cache
Connection: Keep-Alive
Content-Length: 153
Content-Type: application/json

So why this cached GET? I am a bit lost, of course IE/Edge is the corporate default browser. Any ideas on what this could be?
