<p>Hello Everyone:</p>
<p><br>
</p>
<p>I'm a beginner to web development.</p>
<p><br>
</p>
<p>I followed Miguel Grinberg's book and develop the flasky blog system. <span style="font-size: 12pt;">I deployed it to Heroku.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Now I bought a new domain name and resoluted the domain to my Heroku domain. When using the new domain, I found that it can't pass the SSL certification when using https. (Of course, the original Heroku URL is https enabled.) There's
always a red cross on the URL in my Chrome browser.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">I bought a free CA from <span>Symantec and got two files .key and .pem.. Can anybody tell me how to use these two files in my FLASK project and make the https function well?</span></span></p>
<p><span style="font-size: 12pt;"><span><br>
</span></span></p>
<p><span style="font-size: 12pt;"><span>And one more question. When I run my project with http using my own domain name, the user login state can't last long. I frequently need to login again. When I run it in https in Heroku domain name, it works well. Is
that because the browser refresh the cookies under unsafe http browsing?</span></span></p>
<p><span style="font-size: 12pt;"><span><br>
</span></span></p>
<p><span style="font-size: 12pt;"><span>Before reading this book, I have barely no idea about web, HTTP, maybe the question is a little bit silly.</span></span></p>
<p><span style="font-size: 12pt;"><span><br>
</span></span></p>
<p><span style="font-size: 12pt;"><span>I hope someone could help me.</span></span></p>
<p><span style="font-size: 12pt;"><span><br>
</span></span></p>
<p><span style="font-size: 12pt;"><span>Thanks a lot!</span></span></p>
<p><span style="font-size: 12pt;"><span><br>
