Features Recognized and indented brackets and parenthesis in ASP/JSP/PHP, Javascript. XML tags and HTML <table>, <tr>, <td> structural tags and <select> are indented, tags and attributes can be transformed to upper/lowercase. IF, ELSE, FOR, WHILE, SUB structures indented in VBScript mode, in both server code and <script> SSI, <pre>, attribute/code quotations and apostrophes are preserved. Newlines and whitespaces preserved, truncated multiple ones. Lines are not split/concatenated. Other languages are easy to support (TCL, Scheme). Flexible for subtemplates etc - no html/code/javascript correctness checks are performed, except for unpaired code and javascript parenthesis/brackets. Limitations and restrictions: All mentioned limitations or "edge" features tested with IE 6.0, Opera 7.11 and Netscape 4.61. ASP/JSP/PHP in html comment not processed. Support for more VBScript structural keywords and comments easy is to do. <script "quotation" or 'apostrophe'> tag (no script itself) and <pre "q" 'ap'> are transformed to upper/lower case as whole and multiple spaces are not truncated. Browsers accept LANGUAGE attribute case insensitively. When html tags are transformed to upper/lowercase, OnClick and other Javascript-related attribute names are transformed as well; this doesn't make any harm for mentioned browsers. <script/>, and <script> with '>' in quotation/apostrophe or with <% %> and are handled incorrectly - they leave indentation open. The same goes for <pre/> and <pre>. This isn't normally used. (It can be solved by adding other lexical states.) <table/>, <tr/>, <td/>, <select/> are handled correctly. VBscript possibly multiline keywords (END IF, END SUB) are put on the same line. Challenges:

if( ) {%>
	<html-to-be-indented-to-minimum-of-both-parts>
<% } else { %>
	<html----->
<% } %>

if/while ( condition(new ParentClass() { anonymous class code with possibility of if statement }
							)
	)

Programmer's notes: Static objects are not synchronized because of token efficiency - mostly 1 token == 1 char. Should there be a need for extensive multithreading, token state stack and other often used static objects should be added to TokenManager class and synchronized on. Extensibility I chosed special tokens and lexical states. This reflects variability of ASP/JSP/PHP "flow" in a flat manner rather than covering it by a BNF net. While state stack is quite straight-forward, additional tricks are used for issues like <tr/>. Quite a high-traffic but not huge token state-space is combined with stack.
