.htaccess - htaccess 301 redirection using regular expression -

-

this current .htaccess file

rewritecond %{request_filename} !-f rewritecond %{request_uri} !(.*)/$ rewriterule ^(.*)$ $1/   rewriterule ^([^/]+)/$ index.php?p1=$1 [l] rewriterule ^([^/]+)/([^/]+)/$ index.php?p1=$1&p2=$2 [l] rewriterule ^([^/]+)/([^/]+)/([^/]+)/$ index.php?p1=$1&p2=$2&p3=$3 [l] rewriterule ^([^/]+)/([^/]+)/([^/]+)/([^/]+)/$ index.php?p1=$1&p2=$2&p3=$3&p4=$4 [l] rewriterule ^([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/$ index.php?p1=$1&p2=$2&p3=$3&p4=$4&p5=$5 [l]

basically, takes 5 "friendly url folders" , assign value varibles , then, send index.php page

ie: http://www.example.com/ford/focus/grey/  $p1 = 'ford'; $p2 = 'focus'; $p3 = 'grey'; $p3 = 'grey';

so far, good.

now, need integrate 301 instruction (regexp?) in same .htaccess because initially, had parameters :

ie: http://www.example.com/ford/focus/grey/?lang=fr

i need rid of variables because google sees duplicate content (even if i'm using nofollow attribute on languages links)

ie: http://i.want.to.keep/my/url/?and_dump_get_variables  http://www.example.com/ford/focus/grey/?lang=fr http://www.example.com/ford/focus/grey/?lang=en http://www.example.com/ford/focus/grey/?lang=sp ==> http://www.example.com/ford/focus/grey/

logically, instruction should interpreted between first , second block don't know start. hints?

thanks!

as understand want rid of query string , redirect (301 permanent redirect) same url without query string.

the rule below redirect every request has query string:

rewritecond %{query_string} !^$ rewritecond %{env:redirect_status} ^$ rewriterule ^(.*)$ http://%{http_host}/$1? [r=301,l]

1. ? magic -- strip query string

2. desperately need line: rewritecond %{env:redirect_status} ^$. problem may not work on apache setup , cannot give need make work (it works fine on vanilla apache v2.2.17 on windows).

after rewrite (internal redirect) occurred, goes next iteration , apache starts matching rules top again rewritten url. if not add above line, mod_rewrite apply above rule rewritten url form , end all urls rewritten /index.php no parameters @ all.

if above not work, try code below:

# not existing files , folders rewritecond %{request_filename} -f [or] rewritecond %{request_filename} -d rewriterule .+ - [l]  rewritecond %{query_string} !^$ rewriterule ^(.*)$ http://%{http_host}/$1? [r=301,l]

with of # not existing files , folders rule, mod_rewrite stop rewriting after url rewritten /index.php?p1=... format.

in case above not work @ (better -- in addition above -- suggest adding anyway) use <link rel="canonical" href="full_proper_rul"/> in page:

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

-
i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
