The exception handler gets called if a user routing handler throws an error.
```cpp
svr.set_exception_handler([](const auto& req, auto& res, std::exception &e) {
res.status = 500;
svr.set_exception_handler([](const auto& req, auto& res, std::exception_ptr ep) {
auto fmt = "<h1>Error 500</h1><p>%s</p>";
char buf[BUFSIZ];
try {
std::rethrow_exception(ep);
} catch (std::exception &e) {
snprintf(buf, sizeof(buf), fmt, e.what());
} catch (...) { // See the following NOTE
snprintf(buf, sizeof(buf), fmt, "Unknown Exception");
}
res.set_content(buf, "text/html");
res.status = 500;
});
```
NOTE: if you don't provide the `catch (...)` block for a rethrown exception pointer, an uncaught exception will end up causing the server crash. Be careful!
