[PATCH] mod_proxy_html deletes wrong data from HTML when meta http-equiv tag specifies Content-Type behind other meta http-equiv tag
Hi Apache developers, over the time I've accumulated some patches for mod_proxy_html which I would like to get reviewed, and get applied in SVN (best both, trunk and then backported to 2.4). This is something that I feel to owe the Apache httpd community. So, lets first start with a bug that lets mod_proxy_html delete the wrong data from HTML code when a http-equiv meta tag specifies a Content-Type behind any other http-equiv meta tag (Thomas, Ewald, this is issue #21648 in our Mantis). For better understanding of the issue, please consider the following HTML file treated by mod_proxy_html: html head meta http-equiv=X-Dummy-Header content=dummy value style type=text/cssdiv.ok { color: green; } /style meta http-equiv=Content-Type content=text/html; charset=utf8 head body div class=okIf the metafix is not broken, this text should get rendered in green color./div /body /html Without the attached patch, mod_proxy_html will remove the style tag inside the head tag as soon as it parses the meta tag with the http-equiv=Content-Type attribute. With the attached patch applied, mod_proxy_html removes the meta tag with the http-equiv=Content-Type attribute instead. I guess this is what the code intended to do. The attached patch is based on httpd trunk, rev. 1579365. Please provide feedback whether I should file an issue in Apaches Bugzilla or whether this isn't needed in this case.
