I have too sites. one is for Chinese, second is for english. and config as below:

<add key="UseRelatedSiteMode" value="true"/>

<add key="UseFoldersInsteadOfHostnamesForMultipleSites" value="true"/>

I want switch between these two sites.

The first method I use a asp:DropDownList's, and on its onselectedindexchanged event to switch to the another site's same page. But it often error(it only goto the Error.htm and didn't give any error information),  especially it often error when swith between two root pages,  I think maybe the reasons are:

1. bring the viewstates from one site to another site's same page lead to the error.

2.bring the sesson or the cookie  from one site to another site's same page lead to the error.

3. post data to a form with acton="" (when switch between the root pages) lead to the error.

so I give the first method. I use the second method: only use two links to switch to the two sites's same page.

but now it abnomal too:

when I switch to the another site's same page ,sometimes it can success, sometimes it will still stay on the old page, it didn't switch. though the browser's location url  switch to the right url, but the server didn't give me the new site's content. it still give the old site's content.

So I think maybe the server has problem to decide the right site from url. it didn't use the url to decide the site first, it use the session or the cookie the decide the site first?but I have no method to clear the session or the cookie when I use link to switch the sites.

my two sites is www.ipwom.com and www.ipwom.com/en/,  in the site's top-righ corner has two icons to switch the sites, but when after switch several(about 5~6) times ,it will not switch, thought the browser' location url switch right.

So joe,

Could you give some way to solve the problem?

Thanks!

Hi, joe

after research, I found the problem is occurs only when switch between www.ipwom.com and www.ipwom.com/en/ or switch between www.ipwom.com/Default.aspx and www.ipwom.com/en/Default.aspx,switch between others pages didn't have this problem.

when I use asp:DropDownList control to switch, then sometimes it will goto Error.htm.

when I use link control to swith, then sometime it will not switch right, but it will not goto Error.htm.

when I didn't use any control, I open two Chrome tab to get the two site's root page, sometimes it will get the other site's root page, so it has problem too.

I can't found the problem, maybe get the  SiteSettings cache or some place is not right.

But I can resolve the problem by replace Default.aspx in the url with home.aspx.

Thanks!
