Unable to add multiple cookies on WCF service call

[kish_s]

Hi,


I've managed to add multiple cookies in the WCF service outgoing response by adding "Set-Cookie" attribute in the response header. It works great and the cookie is available in all subsequent requests only if there is one cookie but not for multiple cookies.Please refer my below implementation. I'm adding the cookies into the response header by implementing IDispatchMessageInspector interface in order to add cookies in all WCF service method calls if there any pending cookies to be updated in the response.


Sample of Cookies output in the response header

1 Cookie: foo=testcookie1; path=/ --> available in all the subsequent request calls
2 or more cookies: foo=testcookie1; path=/;, foo2=testcookie2; path=/;, foo3=testcookie3; path=/; --> --> only the first cookie available in all the subsequent request calls but not others

For example:

after the setting the cookies, my response header will look like Set-Cookie: foo1=testcookie1;,foo2=testcookie2;, foo3=testcookie3;. If I make another request then the request header cookie contains only foo1=testcookie1; but not these cookies foo2=testcookie2; foo3=testcookie3;. This is where the issue comes. If I set more than one cookie in the response header then it always takes only the first cookie in the subsequent request call.

Please help me to resolve this issue. Thanks in advance for your kind replies.
