Hi
We want to achieve a 10-15% data reduction of the HTML being served by our webserver (generated by JSP pages). This will have an impact on our bandwidth charges from our ISP...
We can achieve this by by simply removing all the "\n\r", "\t characters and replacing repeated occurences of " " (double space) by " " (single space). But we don't want to do this in our source JSP files as they will become unmaintainable/unreadable.
eg <table> <tr> <td>Column 1</td> <td>Column 2</td> <tr> </table>
(69 characters)
becomes
<table><tr><td>Column 1</td><td>Column 2</td><tr></table>
(57 characters), that's an 17% saving for that text block...
I know that we could:
i) write/implement a filter to process the outputstream - BUT we use OSCache (www.opensymphony.com) to cache (included) JSP pages, and we don't want to reprocess cached data using another filter.
ii) use a script to transform or preprocess our JSP pages before they are deployed - simple, but may have code breaking (between dev and live system) or maintenance implications?
iii) create a tag library to process a text block (or another JSP), BUT we've heard a rumour that taglibs can be inefficient (is that true?)
Question: is it possible to use a directive in a JSP page to force the compiler to remove these characters to achieve our desired data reduction?
Are there any other techniques or solutions that anyone else is using?
Thanks
