几天后,我几乎放弃了,但在半夜,我有了一个绝妙的主意,让这一切都发挥作用。如果我对在 64 位模式下运行的网络服务器上的子域进行 ajax 调用,其中的虚拟目录包含在 32 位应用程序模式下运行的站点的索引目录。
第二天睡了个觉后,我开始工作,在 IIS7 中添加了一个新的子域,将虚拟目录添加到了网站的索引目录中。并添加了一个包含请求处理程序的“indexer.asp”页面。

然后我在其中一个以 32 位应用程序模式运行的网站上创建了一个请求页面:
dim FSOA 'return documents file array
'search inside documents
sub DoSearchText(target, indexservice)
'target = search string
'indexservice = catalog name (index service)
dim IndexArray() 'one dimensional array for index result
dim xmlhttp, tempArray, IndexUrl
'url to the 64bit indexer subdomain
IndexURL = ("http://indextest.subdomain.local/indexer.asp?Index="&IndexService&"&Search="&target&"&Size=50")
set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")
xmlhttp.open "GET", IndexURL, false
xmlhttp.send ""
if xmlhttp.status >= 400 and xmlhttp.status <=599 then
response.write " error processing: " &xmlhttp.status &" - "&xmlhttp.statusText
else
tempArray= xmlhttp.responseText
end if
set xmlhttp = nothing
'put result into a array
FSOA= split(tempArray,"|")
end Sub
call DoSearchText("chapter one", "sitebooks")
if isarray(FSOA) then
dim docloop
for each docloop in FSOA
response.write "<div>"&docloop&"</div>"
next
else
response.write "No documents found"
end if

解释:
- 解析索引服务目录名称、搜索字符串、最大结果文档
- 在子域中创建虚拟目录(命名为索引目录),重定向到已索引目录的原始位置
- 添加处理请求调用的 indexer.asp 页面
- 更改原始网页的现有请求对象代码以对上述子域进行ajax调用
好处:
- 从运行在 32 位应用模式的 asp 经典网站向 64 位应用发出 Ajax 请求并返回结果。
- 您还可以包含adobe PDF Ifilter(64 位)来索引 PDF 并阅读 PDF 文件内部。
- 易于更改站点的现有 asp 代码。微小的变化
- 在单独的 64 位池和子域上运行索引器
- 在一个位置添加多个目录,易于维护
- 让不可能成为可能:在 32 位应用模式下运行带有 64 位索引服务的 asp classic
