Guid in Querystring is being transformed somehow <p>I am not sure why this is occuring but here are a few details that may help to find a solution:</p> <ul> <li>It seems to work correctly on most computers firefox and IE</li> <li>It occurs to certain Guids as others work</li> <li>We put the firewall in monitor mode and still occurs</li> </ul> <p>This is the line in PageModify.aspx building the query string: </p> <pre><code>Response.Redirect(string.Format("Editor.aspx?id={0}", pageId, CultureInfo.CurrentCulture)); </code></pre> <p>This is the output of the query string when all goes correctly: </p> <pre><code>https://example.com/Editor.aspx?id=1dfz342b-3a4d-4255-8054-93916324afs6 </code></pre> <p>This is what is viewed in the browser when redirected to Editor.aspx: </p> <pre><code>https://example.com/Editor.aspx?id=1dfz342b-3a4d-xxxxxxxxxxxxxxx324afs6 </code></pre> <p>Of course we get an invalid guid error when this line runs: </p> <pre><code>_PageEditId= new Guid(Request.QueryString["id"]); </code></pre> <p>Has anyone seen this? Could it be IIS settings? Nothing special is being done here and everyone's systems has the same baseline. It occurs to inside and outside customers.</p>
