htaccess / mod_rewrite停止工作—忽略重写规则

Question

I have a website that I wrote and maintain for a client. I am currently hosting it on 1&1. The website was working perfectly up until 3-4 weeks ago. No changes were made to it anywhere in that time frame, the client just noticed that the redirects were no longer working.

The site is set up so that all urls are redirected to a view.php file, which then loads the correct page into the website template using a php include statement.

There are three main test cases:

1. http://www.hazardcontrol.com/factsheets/workplace/industrial-safety should redirect to: /view.php?fs=workplace&p=industrial-safety

2. http://www.hazardcontrol.com/library/topical-index should redirect to: /view.php?f=library&p=topical-index

3. http://www.hazardcontrol.com/factsheets/pdfs/workplace-safety-programming.pdf should NOT redirect

When it first broke (loaded the view.php page, but can't find the correct content page to include), I used a php echo statement in the view.php file to find out what the GET variables were that were being passed. Consistently they turned out to be f=reset: and p=view, no matter what url was tried.

I tried editing the htaccess file to update it and make sure everything was clean, simple, and correct. Now, case 1 is working fine. Case 2 was working 5 minutes ago, but isn't now - it tries to redirect to the view page. Case 3 is going straight to the '/library/topical-index.php' page that actually holds the content instead of redirecting to the view.php page so that it loads inside the template. Both htaccess files are below.

Thanks in advance for any help you can provide!

Original htaccess file

(which WAS working. I did try calling 1&1, but they assured me they hadn't done anything except update Apache a little over a month ago, but that was before my site broke so it MUST be my script).

#Rewrite dynamic URIs as static/flat URIs for user ease and search engine happiness
RewriteRule ^(\.pdf)$ - [L]
RewriteRule ^factsheets/([^/\.]+)/([^/\.]+)(.*)$ view.php?fs=$1&p=$2 [L]
RewriteRule ^([^/\.]+)/([^/\.]+)(.*)$ view.php?f=$1&p=$2 [L] 

Answer 1

To get all three cases working, I changed

RewriteRule ^(\.pdf)$ - [L]

to

RewriteRule ^(.*\.pdf)$ $1 [L]

and the PDF did not redirect. This worked because the regular expression ^(.*\\.pdf)$ matched factsheets/pdfs/workplace-safety-programming.pdf .

To troubleshoot I used http://htaccess.madewithlove.be/ .
