回答：證書中"簽名算法"和"微縮圖算法"有什麼區別?java
證書中「簽名算法」是指：上級CA（根CA上級CA是指本身）頒發證書時，對證書待簽名數據進行簽名的算法。例如簽名算法sha1RSA，是先對主題（用戶）證書的待簽名數據，進行sha1運算，而後在用上級CA私鑰進行RSA加密運算；
理解微縮圖算法，先要理解微縮圖是什麼意思。微縮圖是微軟本身提出來的一個概念。和證書rfc標準沒有任何關係。微縮圖是對整個證書進行hash運算，生成一段數據，這一段數據就是所謂的微縮圖數據。在windows下就是微軟的證書工具最後面兩個屬性（用微軟證書查看工具，一看就會發現爲微縮圖算法、微縮圖）。微縮圖算法指對整個證書進行hash運算時，所採用的數學運算算法。好比sha1或者md5。請你們不要迷惑了。

X表明你想插入的頁碼
一、將鼠標定位在第X-1頁的最後一個字符後
二、選擇「插入-〉分隔符」；在「分節符類型」選項中，選中「下一頁」；按「肯定」
三、將鼠標定位到第X頁
四、選擇「插入-〉頁碼」；將「首頁顯示頁碼」勾上（由於頁面默認是「首頁不一樣」）
五、按「格式」鍵；勾點「起始頁碼」，選擇「1」
「將第X頁設爲第1頁的問題」就解決了；但還要執行下面這一步
六、雙擊第X頁的頁腳，出現「頁眉和頁腳」工具圖標，同時頁腳區域會顯示「與上一節相同」的提示（若是沒有此提示，下面的步驟就不用執行了）
七、點擊「頁眉和頁腳」工具圖標中「連接到前一個」按鍵後，頁腳區域顯示的「與上一節相同」的提示消失；
八、點擊「頁眉和頁腳」工具圖標中「關閉」按鍵；至此就ok了
對第X-1頁及以前頁無頁碼的處理：
雙擊第X-1頁的頁腳，將顯示頁腳數字的欄位刪掉便可安全

IMAP (Internet Message Access Potocol) 是一種用於郵箱訪問的協議，使用IMAP協議能夠在Client端管理 Server上的郵箱，它與pop不一樣，郵件是保留在服務器上而不是download到本地，在這一點上IMAP是與Webmail類似的。但IMAP有比Webmail更好的地方，它比webmail更高效和安全，能夠離線閱讀等等，若是想試試能夠用Outlook Express，只要配好一個賬號,將個人郵件接收服務器設置爲IMAP服務器就能夠了。cookie

Bernie zimmermann 在blog上對uri與url的區別的解釋:
"URI stands for Universal Resource Identifier and URL stands for Universal Resource Locator. Often times people use the terms interchangably, which is not entirely correct. A URL is a subset of the URI popular protocols. These are protocols (http://, ftp://, mailto:). Therefore all URLs are URIs. The term URL is deprecated and the more correct term URI is used in technical documentation. All URIs are means to access a resource on the Internet and are a a technical short hand used to link to the resource. URIs always designate a method to access the resource and designate the specific resource to be accessed."
So...my terminology is apparently way out-dated and I need to start saying "URI" instead of "URL." Why? Because anything that has been deprecated is bad news (remember the evil <blink> tag?). Now I know, and knowing is half the battle.

comment out
對程序的源碼和軟件的設定文件等進行修改時，並不是馬上消除想要消除的內容，而是進行comment化，使其暫時不運行的操做。
處理源碼和設定文件的編譯等程序中，可以用特殊的記法使指定的部分不被解釋，讓使用方法和註釋包含在文件中。利用這個功能，能夠嘗試性地讓想要消除的部分comment化。想讓comment化的內容恢復到原狀時，只需把comment記法的部分解除就能夠馬上恢復到原來的狀態。

I'm not sure I understand what you're asking.
The CASReceipt is intended to expose a JavaBean properties all the
information about the CAS authentication that your application could
plausibly use to translate into authentication appropriate to your
application (session attributes, REMOTE_USER field, ThreadLocal,
encrypted cookie -- whatever it is that your application was going to do
to model the authenticated user).
Are you asking how you know that it is the CAS Client that placed the
CASReceipt into the session? I guess the answer to that is that you
don't. Code with access to the HttpSession needs to be trusted within
your application.
Hope this helps,

一直就不知道load-on-startup的具體含意是什麼,在google上找了一些解釋, 說法各類各樣,最後俺仍是搬來了Servlet specification, 裏面的內容絕對準確,呵呵....
The load-on-startup element indicates that this servlet should be loaded (instantiated and have its init() called) on the startup of the web application. The optional contents of these element must be an integer indicating the order in which the servlet should be loaded. If the value is a negative integer, or the element is not present, the container is free to load the servlet whenever it chooses. If the value is a positive integer or 0, the container must load and initialize the servlet as the application is deployed. The container must guarantee that servlets marked with lower integers are loaded before servlets marked with higher integers. The container may choose the order of loading of servlets with the same load-on-start-up value.
