* $Log: urlmatch.c,v $
+ * Revision 1.45 2008/06/21 21:19:18 fabiankeil
+ * Silence bogus compiler warning.
+ *
+ * Revision 1.44 2008/05/04 16:18:32 fabiankeil
+ * Provide parse_http_url() with a third parameter to specify
+ * whether or not URLs without protocol are acceptable.
+ *
+ * Revision 1.43 2008/05/04 13:30:55 fabiankeil
+ * Streamline parse_http_url()'s prototype.
+ *
+ * Revision 1.42 2008/05/04 13:24:16 fabiankeil
+ * If the method isn't CONNECT, reject URLs without protocol.
+ *
+ * Revision 1.41 2008/05/02 09:51:34 fabiankeil
+ * In parse_http_url(), don't muck around with values
+ * that are none of its business: require an initialized
+ * http structure and never unset http->ssl.
+ *
+ * Revision 1.40 2008/04/23 16:12:28 fabiankeil
+ * Free with freez().
+ *
+ * Revision 1.39 2008/04/22 16:27:42 fabiankeil
+ * In parse_http_request(), remove a pointless
+ * temporary variable and free the buffer earlier.
+ *
* Revision 1.38 2008/04/18 05:17:18 fabiankeil
* Mark simplematch()'s parameters as immutable.
*
* Parameters :
* 1 : url = URL (or is it URI?) to break down
* 2 : http = pointer to the http structure to hold elements.
- * Will be zeroed before use. Note that this
- * function sets the http->gpc and http->ver
- * members to NULL.
- * 3 : csp = Current client state (buffers, headers, etc...)
+ * Must be initialized with valid values (like NULLs).
+ * 3 : require_protocol = Whether or not URLs without
+ * protocol are acceptable.
*
* Returns : JB_ERR_OK on success
* JB_ERR_MEMORY on out of memory
* or >100 domains deep.
