在新窗口中设置页面重定向的会话值

Question

Searchbox.cs文件

protected void SearchButtonClicked()
{
    Session["returnToSearch"]="/content-search-result?searchtext=test&searchmode=anyword";
    Response.Redirect("/detailPage.aspx");
}

on detailPage.aspx

 <a href='<%= Session["returnToSearch"] %>'>Return to Search</a>

我已经在cs文件中设置了会话，并且如果使用target_blank重定向到在新窗口中打开的另一个页面。如果我搜索测试returnToSearch加载前一个值，如果存储在session else空值中，但如果我重新加载页面，它将设置正确的更新值。

searchbox.aspx

   <div class="search-box">
            <div class="searchBox" id="SearchBox_pnlSearch">
                <label style="display: none;" id="SearchBox_lblSearch" for="SearchBox_txtWord">Search for:</label>
                <input type="text" class="form-control" id="SearchBox_txtWord" maxlength="1000" autocomplete="off">

                }

            }
