Hi,

When SharePoint search returns search results containing links to blog articles, the first time user tries to enter the link results in "404 NOT FOUND" error. When trying the link again (by going back with browser back button and clicking again on the same link) it works.

Firstly, when doing a search, SharePoint search returns links to blog posts in this format: http://mysite/personal/jam/Blog/Lists/Viestit/ViewPost.aspx?ID=3

After clicking on the search result, user is redirected to non-existing URL, and user gets blank screen with "404 NOT FOUND" error: http://mysite/personal/jam/Blog/Lists/Posts/Post.aspx?List=f7f62f92%2Dfb73%2D4c24%2Da933%2Dee7608a825a3&ID=3&Web=6120a040%2D9d26%2D4c09%2D8b5e%2Dc3a11566b827

Then when going back, and clicking again on search result link, user is redirected to correct URL: http://mysite/personal/jam/Blog/Lists/Viestit/Post.aspx?List=f7f62f92%2Dfb73%2D4c24%2Da933%2Dee7608a825a3&ID=3&Web=6120a040%2D9d26%2D4c09%2D8b5e%2Dc3a11566b827

If you look at the link closely, you see that "Posts" has been replaced with "Viestit", as MySite/Blog language is Finnish, not English. 

After this, link to blog posts by that user work fine UNTIL IISRESET is run, after that it again requires one-time 404 error page until users get to the blog page.

In ULS log, I see SharePoint doing various URI mapping, but they don't make much sense as it's mapping MySite URI to intranet site URI, and then finally mapping it to the incorrect URI with incorrect list URL "Posts".

Why does SharePoint resolve links to incorrect URLs and how to make it working also on first blog page access? Using August 2013 CU.
