1,I don't know whether the IE caching dynamic pages(showModuleDialog()'s popup windows)
2,How to judge whether the B page by caching, cache in where?
3,Why not send the request?
perents window A open sub window B use showModuleDialog().
A page send request to Apache HTTP server then Apahce transport to AP server to excute INIT() Fanction.
INIT() Methed put some values into AP server's Memory to wait next operation.(..like KbnFlag=2..)
B page popup,There is a button that is named [Search] for search request.
click [Search] button ,B page sand a request to Apache then Apache transport to AP Server to excute isExcu() Fanction.
isExcu() use A's values in memory compear with B's values.(..like[(b.KbnFlag).eq(A.KbnFlag)]..)
A request URL1 =[XX/Mar/20XX:XX:XX:XX +0900] "GET /abcd/someTodo/search?requestId=BInit&ProcId=123456&ProcMode=4&DetailNo=041&KbnFlag=2 HTTP/1.1" 200 0 9104
B request URL2 = /abcd/someTodo/search?requestId=Search HTTP/1.1" 200 0 13040
click [Search] button ,B page popup.
But No request A(URL1) send to Apache(i can't find the reuqest in access.log).
INIT() didn't excuted.No values were put into memory.
AP server didn't received the request A. Nothing in ap.log about INIT() operation.
At this time B page popup,User didn't Know request is missing.User click [Search] button.Error occurred!! isExcu() throw exception.
In ap log i found this : Attribute [KbnFlag] value is invalid.AP server can not found the KbnFlag's value.
This error occurred 3 times in 1 year.To reproduce the difficulties.For unknown reasons.
3, I guess maybe page B was cache by IE8.
4, I guess maybe page B was cache by Apache HTTP Server.
But I can't find the evidence

Additional remarks !
The same settings in page A and B:
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
The purpose is to keep this page no cache
2, Apache HTTP Server 2.2 load the cache_module and mem_cache_module but no set.
3,IE8 set Internet temporary file - > temporary file version automatically identified
