    <p>I am sending two different https header to different address on same host. I am getting the same response from both test() and test1() functions...

    2. COMaybe the answer is the very same error message in both cases? BTW: You question doesn't has anything to do with C++ can you please remove the C++ tag?

    3. COIt would be more productive to show the requests you send and the responses you get, instead of the code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
