Paul,
Put '@' in front of the strings or use '\\' instead of '\'. Something like this:

if (strURL.Trim().EndsWith(@"\"))
	URL = strURL.Trim()+@"aesys\default.aspx?clearcache=true";
else
	URL = strURL.Trim()+@"\aesys\default.aspx?clearcache=true";

or

if (strURL.Trim().EndsWith("\\"))
	URL = strURL.Trim()+"aesys\\default.aspx?clearcache=true";
else
	URL = strURL.Trim()+"\\aesys\\default.aspx?clearcache=true";

Einar
