I'm getting strange 500 internal error and 403 errors when i try to search my blog. here is my code:

FeedQuery query = new FeedQuery(); Service service = new Service(); query.Uri = new Uri([feed url]); query.Query = searchQuery; AtomFeed feed = service.Query(query);

the strange thing is that i get the 500 error if my feed url uses this style:

http://[blogname].blogspot.com/feeds/posts/default

for example: http://ppkkangs.blogspot.com/feeds/posts/default

and 403 error if my feed url uses this style:

http://www.blogger.com/feeds/[blogid]/posts/default http://www2.blogger.com/feeds/[blogid]/posts/default (note the www2)

for example: http://www.blogger.com/feeds/3260147694387237509/posts/default http://www2.blogger.com/feeds/3260147694387237509/posts/default

and by the way which feed url is recommend best because i think that only one is real the others are aliases.
