Severity: 3-Major


HTML page may contain a very long 'data:' URL. Portal Access cannot handle such URLs correctly.


The rewrite plugin cannot process HTML pages with very long URLs and restarts. The page is not sent to the end user client; web application may not work correctly.


HTML page with very long 'data:' similar to the following example: data:image/png;base64,... Such URLs might be several megabytes long.


There is no workaround at this time.
