Its a strange problem!

I use a webbrowser control(c#) to access one site like 'a.b.c'.

It first work well. after the webbrowser control continue to acces the site for a

long time,It return an errorcode mean

"connection timeout" I use some tool to check its net status.and I found that the

webbrowser control did not access the net (no data send to the net). but if I use the

webbrowser to someother site like 'd.e.f'. it work well. only the site 'a.b.c' can't

work.

I have used wininet.dll api like 'DeleteUrlCacheGroup,DeleteUrlCacheEntryA' to
clear cache,The problem still happened.

somebody know what's wrong?thx!

It could just be site traffic to "a,b,c"?

Solution 1

did you try wbBrwsr.Refresh();

Actually you are using the IE engine to render the webpage in your WebBrowser control. Does the same thing happens when you browse using normal IE ?
