browser - static images aren't caching with php-generated page -

-

Our website was just changed to be generated by mod_rewrite and php scripts.

All picture formats follow: 

  & lt; Img src = "/ images / header.png" /> ;

I should avoid caching completely because the PHP parser needs to dynamically handle every page on each request; However, the download overhead of large images is cumbersome on each page load.

I will ideally provide the header for "cache-control: no-cache, sure-modify" and "expiry: some_date_in_the_past", to force PHP script to be re-verified.

Why is not the browser caching static images in all pages with consistent href values?

You can tell in your .htacess file that which file extensions you have fixed some headers For content you want to apply, you can provide header and dynamic content that ends in the future, you can write cache-not the modal cache has to be modified again. 

  & lt; IfModule mod_deflate.c & gt; & Lt; File match ". (Js | css | html | php) $" & gt; SetOutputFilter DEFLATE & lt; / FilesMatch & gt; & Lt; / IfModule & gt; & Lt; IfModule mod_expires.c & gt; & Lt; File match ". (Gif | jpg | jpeg | png | swf | css | js | html? | Xml | txt] $" & gt; expiresDefault Access Type "Diffelt Plus 10 Years" Type Closing Image / X-icon A 604800 header set cache-control "Max-age = 290304000, public"

Like this example I have a lot Only in the future all the different static file matches have finished the headers.

Note: File magnets tag and file extension .htacess file inside any of your applications Are placed in Holder and it gives these settings for that folder.

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
