+# NAME
+
+CURLOPT_HTTPGET - ask for an HTTP GET request
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPGET, long useget);
+~~~
+
+# DESCRIPTION
+
+Pass a long. If *useget* is 1, this forces the HTTP request to get back to
+using GET. Usable if a POST, HEAD, PUT, etc has been used previously using the
+same curl *handle*.
+
+When setting CURLOPT_HTTPGET(3) to 1, libcurl automatically sets
+CURLOPT_NOBODY(3) to 0 and CURLOPT_UPLOAD(3) to 0.
+
+Setting this option to zero has no effect. Applications need to explicitly
+select which HTTP request method to use, they cannot deselect a method. To
+reset a handle to default method, consider curl_easy_reset(3).
+
+# DEFAULT
+
+0
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
+
+    /* use a GET to fetch this */
+    curl_easy_setopt(curl, CURLOPT_HTTPGET, 1L);
+
+    /* Perform the request */
+    curl_easy_perform(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
