+ * Revision 1.15 2007/01/28 16:11:23 fabiankeil
+ * Accept WebDAV methods for subversion

+ *
+ * Revision 1.14 2007/01/06 14:23:56 fabiankeil
+ * Fix gcc43 warnings. Mark *csp as immutable
+ * for parse_http_url() and url_match().
+ * Replace a sprintf call with snprintf.
+ *
+ * Revision 1.13 2006/12/06 19:50:54 fabiankeil
+ * parse_http_url() now handles intercepted
+ * HTTP request lines as well. Moved parts
+ * of parse_http_url()'s code into
+ * init_domain_components() so that it can
+ * be reused in chat().
+ *
+ * Revision 1.12 2006/07/18 14:48:47 david__schmidt
+ * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
+ * with what was really the latest development (the v_3_0_branch branch)
+ *
* Revision 1.10.2.7 2003/05/17 15:57:24 oes
* - parse_http_url now checks memory allocation failure for
* duplication of "*" URL and rejects "*something" URLs

+ * Description : Splits the domain name so we can compare it

+ * same code is required in chat in case of
+ * intercepted requests.
+ *
+ * Parameters :
+ * 1 : http = pointer to the http structure to hold elements.
+ *
+ * Returns : JB_ERR_OK on success
+ * JB_ERR_MEMORY on out of memory
+ * JB_ERR_PARSE on malformed command/URL
+ * or >100 domains deep.
