title: HTTP client example
---
To create an HTTP client, follow this pattern:
1. Create an outbound connection by calling `mg_connect_http()`
2. Create an event handler function that handles `MG_EV_HTTP_REPLY` event
Here's an example of the simplest HTTP client.
Error checking is omitted for the sake of clarity:
```c
#include "mongoose.h"
static const char *url = "http://www.google.com";
static int exit_flag = 0;
static void ev_handler(struct mg_connection *c, int ev, void *p) {
if (ev == MG_EV_HTTP_REPLY) {
c->flags |= MG_F_CLOSE_IMMEDIATELY;
fwrite(hm->message.p, 1, hm->message.len, stdout);
putchar('\n');
exit_flag = 1;
}
}
int main(void) {
struct mg_mgr mgr;
mg_mgr_init(&mgr, NULL);
mg_connect_http(mgr, ev_handler, url, NULL, NULL);
while (exit_flag == 0) {
mg_mgr_poll(&mgr, 1000);
}
mg_mgr_free(&mgr);
return 0;
}
```
